FAQ
1. Help I suck what do.
So you're playing Demon and there's a bunch of weird skills you don't understand and a bunch of weird monsters you don't recognize because you aren't a professor of world mythology. Well lucky you, Examine, right click and hover over everything you find, and you'll get explanations of literally everything.

2. Help this game is hard.
Demon has very few 'popcorn' encounters. After Tower:1, monsters start coming in packs of 5+ pretty much exclusively, and until you have more skills you probably can only kill 1 or maybe 2 demons by yourself. Luckily you can recruit demons, and you should do so. A lot. It's kinda the point of this game. If you don't have 6 demons, you should be recruiting anything new you find. Anyway, basically any given encounter can potentially fuck you up, and escape items are VERY RARE. To git gud at Demon, you need to treat every encounter with respect and efficient tactics.

3. So what, I'm like a Pokemon trainer?
In a sense, yes. You need to start assembling a team of demons to kill all the other teams of demons, and each one of your turns is incredibly valuable in combat. You'll be using your own abilities, unsummoning your demons that are wounded or inappropriate for the situation, summoning new ones, linking with enemy demons to recruit them. (Even if you have no intention of keeping them around. Negotiating with some demons and discarding them as soon as you get them is a good way to cut down the lethality of some packs such as Zar.)

4. How do I tell which demons are good?
(Almost) all demons are useful and can be worked into a team; each has its own niche. Be open minded and willing to experiment.

5. Okay then, what are stat points, and how do I tell what stats are good?
Each time you level up, you get 5 stat points to allocate to your stats. You want Strength for slash/impact/pierce abilities, Magic for healing and nonphysical attacks, Vitality for bonus HP and resistance to debuffs, Agility for dodging and accuracy, and Cunning is for debuffs. Anyway, use your common sense and try things out.

6. What starting relic should I choose?
Crown of Glory: Supportive melee frontliner
Eye of Dragon: Breath attack melee frontliner
Faithful Heart: Buffer/Healer/Support
Hand of the Dead: Debuff melee frontliner
Orb of Power: Magic glass cannon
Titan's Fist: Tanky melee frontliner
Vodun mask: Debuff/Magic

Check out the section below about suggested builds too.

7. What are relic upgrades, and which ones should I get?
Each relic starts with two predetermined relic upgrades, and you can upgrade your relic at Level 5, 15, 25, etc. Upgrade relics can increase the number of maximum allies you have, let you summon and dismiss allies instantly, give or save you credits (credits are the currency used to upgrade yourself and demons), and some other neat stuff. As of the time of this writing, relic upgrades were released very recently so I can't say which are the best.

8. How do I beat the game?
Get to the portal at Tower:20. Winning starts a new game. Nothing but your score carries over to the new game.

9. Is there a manual?
Yes, READ THE MANUAL. You can find it by pressing "?" while playing Demon. (You can't access it from the start screen. You need start a new game.)

Section 1: General Tips
1. On floors 1-2, recruit every demon you can.
2. Have at least 2 demons summoned when exploring that (hopefully) do not share common weaknesses. Preferably, one is a healer equipped with Calm, one is durable, and none have a Mind weakness. (Mind weakness leaves them vulnerable to being CC'd immediately against some enemies.)
3. Be stingy with your credits. In general, eschew upgrading your early demons since they will be deleted soon enough.
4. My personal strategy for spending credits pre-Anomaly: upgrading yourself with abilities key to your strategy, teaching your Gandayah Healing Charm, and sacrificing your Fairy to fuse with your Gandayah to get a Lifegiver Gandayah. Lifegiver Gandayah is an amazing healer that stays relevant all the way to Tower:20. Useful, easily found moves to teach it: Lifegiver, Calm, Absolution, and Draw Wounds. (If you get the Aracadia branch on D:3, consider delaying the fusion if you want to recruit Artemis since having 2 healers for that link is very helpful. Also, if you really want to get Artemis, spending credits to teach your demons Souleater may be necessary.)
5. That having been said, the strategy space of Demon is mostly uncharted, and you should experiment to see what works for you.
6. Paying to restore a demon is usually never worth it because it cripples your team development. It's fine if you do it near the top of the Tower since your team doesn't have much room to grow at that time.
7. Scrolls of magic mapping should be used at Tower:20 if you have one left. Helps you go straight for the exit instead of getting bogged down by tough foes.
8. If you see a portal to another branch, don't be afraid to take it. There is never a good reason to skip it.

-----
Section 2: Combat Tips
1. Look at the abilities of every enemy you meet. This includes summoners. You should also check what relic upgrades they have.
2. Position your healers so they maintain sight of your team. If your healer turns into a shimmering blue blob, that means it can't see you and won't be able to heal you.
3. Poison debuff is dangerous. Afaik, poison deals a percentage of your health as damage, and eating 3 stacks of Poison can be a death sentence.
4. You, the player character, can be affected by Charm.
5. Killing a summoner too quickly can be a bad thing since all of their surviving demons will spawn around you. Yes, they will be debuffed, but fighting against 6 demons can be tough. You can recruit some of them to make the crowd more managable.
6. Pure stones can restore MaxHP lost from attacks like Vigor Siphon and Void Touch.
7. Don't be afraid to spend consumables to save your life. Those wind cards (basically blink scrolls) in your inventory are useless if you're dead.
8. Chakra stones can restore more health than a heal stone when used on a healer since the healer gets 50 SP to use.
9. Take the time to understand the different types of attack ranges. In particular, Ranged Direct doesn't require a clear shot.
10. Above all, your life matters most. Losing demons is better than losing your life.

-----
Section 3: Recruitment Tips
1. To prepare for the Anomaly side branch, recruit at least one fire-resistant demon. You will need it. I prefer a Malingee and Kasha.
2. Wanted a specific demon type that spawns on the current floor, but it never spawned? Use a trouble chime to spawn an enemy mob.
3. Some consumables inflict debuffs that can help you recruit high speed demons that want you to chase them. (Under certain conditions, you can recruit any high speed demon without using ANY abilities or consumables and without being fast yourself. I'll let you figure this one out.)
4. Linking that involves fending off packs of enemies should be done in as tight of a hallway as possible. A small room works too, but make sure that you can see every corner of the room. Otherwise, enemies will spawn from the walls and make life much harder.
5. Some negotiations don't have a penalty for failing. Do these because you might get lucky and nab a good demon for cheap.

Section 4: Shit That Will Kill You And Your Demons
Raicho-Very fast electric birds. Let your demons tank the attacks rather than you. Switch out your demons as they get low. Not much to say, really.
Ukobach-Ranged fire attacks that hurt. Let your fire-resistant demons tank the attacks. Once they run out of SP, go for the kill.
Zar-Can inflict Panic debuff. The moment you see a pack, recruit one to have a source of Calm.
Vikhor-Super fast melee unique. Comes with a flock of modified Raicho. Killing the Raichos can be easier than killing Vikhor.
Fotia-Like Ukobach, but worse. The source of many splats in the Anomaly branch. See Ukobach.
Paracelsus-A summoner with defensive abilities and heals. Many of his demons are weak to Light and Dark.
Liothe-A summoner that can be complete BS. Inflicts debuffs and has a self-heal that has its cooldown reduced when he's damaged. Kill his demons first.
Akateko-Can deal MaxHP damage quick, fast, and in a hurry. Bring in a dark-resistant demon to tank. If you don't have one, regularly switch out demons when fighting to spread out the MaxHP damage among your team. If you're desperate, link with an Akateko, run away, let it die. Keep doing this until one Akateko is left.
Charlisse-Can deal MaxHP damage and Ice damage. Blinks all over the place at low health. Besides the obvious dark and ice-resistant demons, use a demon with a gap closer like Pounce to lock him down.
Breska-A summoner with lots of physical damage. Be aware he has Leap Attack, which is a Ranged Direct move. This means he doesn't need a clear shot to leap to you.
Reprobus and Mordecai-Reprobus can Breath Fire and immediately refresh its Breath Fire cooldown thanks to Second Wind. Mordecai can leap in, Mighty Roar (a physical breath attack that can stun), and smack you around. They come with an entourage of enemies that can get on top of you using Bull Rush. Spread out your demons to minimize the Breath Fire and Mighty Roar damage. My recommendation is to kill everything but Reprobus and Mordecai first. If you want to recruit Reprobus
Abatwa-Shoots poison needles. One turn you see them, the next turn you're heavily poisoned. Even body-resistant demons have a hard time.
Antoria-Can be thought of as an optional final boss of the game. Don't fight him.

Section 5: Player Builds
These builds are ones I and other players have won with before.
NOTE: You don't have to keep the suggested demons. It's fine if you want to learn their abilities then delete them.

---
Blasty Casty Build
Massive amounts of magic damage with excellent type coverage that wipes out swathes of foes in a few button presses. Sure, you are weak to all physical attacks, but that's the price to pay for ultimate power. From what I know, the most popular build for popping your Demon win cherry.

Relics:
Orb of Power-Fire/Electricity/Mind/Dark/Buff (I prefer Buff) and Ice (Doesn't have to be Ice, but Ice seems to be the strongest option)

Stats To Get:
If you want to go full glass cannon, put everything in Magic.
A more balanced approach is 3 Magic and 2 Vitality.
Add a little to Cunning if you are Dark and Ice, assuming you want to use the ability Hex.
Add a little to Agility if you are Elec and Ice to keep Lighting Bolt accurate.

Abilities to Learn:
Core:
SP boosting abilities (Vigorous, Tireless, Second Wind, Ritualist)
Any magic damage ability that you can get your hands on
Optional:
Defensive abilities (Most notably, Block Physical)
Buff supporting abilities (Only if you picked Buff. Rabblerouser, Blessweaver)
Passive synergizing with your elemental attacks
Self buff abilities (e.g. Vehemence)

Sample Ability Sets:
Orb of Power-Buff and Ice-Haste, Might, Frost Ring, Ritualist, Headwind, Vigorous, Innocence, Winterkill
Orb of Power-Dark and Ice-Vigor Siphon, Snuff Out, Frost Ring, Light Dart, Vehemence, Tireless, Vigorous

Which Demons To Recruit:
Your options are very open. Here are a few:
Light Dart user (Aithir)
Vigor Siphon user (defeating Charlisse)
Snuff Out user (Chindi)
Ritualist user (Jinn, defeating Antoria)
Vigorous user (defeating Zaiji, Pele)

Which Demons To Have Summoned While Exploring:
Healer, frontliner, foo

Tips
-Stay in the back and cast your spells. Watch out for gap closer abilities like Leap Attack or Haunt.
-Ritualist is an incredible passive that reduces the SP cost of all magic abilities with 25 or more SP cost by 10 (with a small catch). The moment you see a Jinn, try to recruit it to get Ritualist. Jinn appear in the last few floors of the Tower, so save a few credits for that moment.
-Teach Refresh to your demons that don't need SP to give yourself free SP

Veil Tank Build (Credit to mbj)
Veils are passive abilities that trigger deal damage and/or debuff adjacent enemies that damage you. Combined with Malleable, which boosts healing received, and healers, this build makes opponents will kill themselves just by being near you.

Relics:
Crown of Glory-Mind/Dark/Debuff (Why these 3? The other options give you a Dark weakness, which is terrible for a front liner) and Electricity
Hand of the Dead-Any (I prefer Dark/Debuff) and Body
Titan's Fist-Slash and Fire/Electricity/Ice (I prefer Electricity since the Storm Veil is the rarest Veil to come by)

Stats To Get:
Early on, put everything in Vitality.
Later, put 3 or so in Vitality and invest in Strength, Magic, or Cunning, depending on the veils I find. Strength for veils that deal physical damage, Magic for veils that deal magic damage, and Cunning for debuff veils.

Abilities To Learn:
Core:
Malleable
As many veils as possible Veils (Best Veil is Alluring Veil from Pele.)
Optional:
Regenerate (Synergizes well with Malleable. Gives you something to spend your SP on when it's too dangerous for you to tank. Can be learned from defeating the hero Zaiji.)
Abilities that make you harder to kill (e.g. Protect, Juggernaut)
Gapcloser abilities (e.g. Leap Attack)

Sample Ability Sets:
Titan's Fist-Slash and Elec-Regenerate, Alluring Veil, Counterattack, Storm Veil, Fiery Veil, Arctic Veil, Poison Veil, Malleable
Crown of Glory-Debuff and Elec-Regenerate, Fiery Veil, Arctic Veil, Storm Veil, Dazzling Veil, Choking Veil, Alluring Veil, Malleable

Which Demons To Recruit:
Malleable user (Slime)
Fiery Veil user (Kasha, Fotia)
Arctic Veil user (Asrai, defeating Charlisse)
Choking Veil user (Ghoul, Python)
Poison Veil user (Blob, Apis)
Spiny Veil user (Chupacabra)
Dazzling Veil user (Shoggoth)
Alluring Veil user (Pele)

Which Demons To Have Summoned While Exploring:
Two healers, foo

Tips:
-Remember that you can't tank everything. Check your healers' SP to ensure that they have enough SP left.
-Fair warning: The build requires some luck. If the right demons don't spawn, no veils for you.

Dirty Needles Build (Credit to mbj)
Needle Shot by itself does ok damage. Needle Shot with the right passives can poison, silence, and inflict all sorts of nasty debuffs. Don't forget to pack some SP boosting moves to compensate for the high SP consumption.

Relics:
Hand of the Dead-Slash and Movement (The harder of the two to pull off; you must recruit either Artemis or a Centaur to get access to a ranged physical attack. The benefit is having guaranteed Terrifying.)
Vodun Mask-Pierce and Pierce

Stats To Get:
Put 1 in Agility and 4 in Cunning.

Abilities To Learn:
Core:
Some physical projectile attack that doesn't have a Luck cooldown (Needle Shot, Paralyzing Needle)
As many physical debuff passives as possible
SP boosting abilities (Vigorous, Bloodlust, Tireless, Second Wind)
Optional:
Leadership
Vehemence

Sample Ability Set:
Vodun Mask-Pierce and Pierce-Needle Shot, Venmous, Numbing, Vigorous, Bloodlust, Blood Rot, Flesh Rot, Brain Knocker

Which Demons To Recruit:
Arc Needle user (Artemis)
Needle Shot user (Centaur)
Tireless user (Gandayah)
Bloodlust user (Artemis, Python)
Infectious user (Lots)
Venomous user (Artemis)
Crippler user (defeating Mordecai)
Terrifying user (defeating Mordecai)
Crusader user (Ehlose)
Blood Rot user (Chindi)
Flesh Rot user (Blob)
Heavyhanded user (Oni)
Numbing user (Turdak)
Vigorous user (Pele)
Brainknocker user (Python)

Which Demons To Have Summoned While Exploring:
Healer, frontliner, foo

Tips:
-Low Profile is nice to have on your demons since you can shoot through them, but I found it's not necessary.
-Don't get only Body related passives (Infectious, Venomous, Numbing, Blood Rot, Flesh Rot). Add in passives of other elemental type.

Pure Buff Build
Want your demons to do all the work? Don't mind mashing the wait button? Look no further! With the right abilities and demons, you can cast your buffs, sit back, and relax during fights.

Relics:
Orb of Power-Buff and Defense/Movement

Stats To Get:
Put 5 in Vitality.

Abilities To Learn:
Any of these will work:
Escape abilities (Dash, Swiftness)
Defensive abilities (Reshape, Block Physical)
Buff supporting abilities (Rabblerouser, Blessweaver)
SP boosting abilities (Tireless, Vigorous, Second Wind, Ritualist)
Other buff abilities (e.g. Protect)

Sample Ability Set:
Orb of Power-Buff and Defense-Haste, Might, Triad Ward, Swiftness, Dash, Rabblerouser, Blessweaver, Vigorous

Which Demons To Recruit:
I don't feel like listing out all the demons here. Plus, examining each demon to see if their abilities are what you want is a good habit to get into.

Which Demons To Have Summoned While Exploring:
Healer, frontliner, frontliner or caster

Tips:
-Buff priority should be Frontliners > Casters > Healers
-Apply Haste first on a demon then Might. This helps frontliners run to their foes faster.
-Might doesn't boost the strength of healing.
