HMC No Upgrade Challenge

This pastebin sums up my strategies for all forced fights in Helen's Mysterious Castle without upgrading any equipment. So far, I have reached the Four Lords where one battle is truly impossible. But only one!

Slime: Longbow x3
Goblin: Longbow x2, Wooden Shield until Great Swing, Longbow x2 OR Longsword
Skeleton: Longsword, (Wooden Shield x3, Longbow, Wooden Shield x2, Longbow)
Mummy: skipped via runaround
Golem: Thunder x3
What is this!?: Broadsword unless Longbow has better value due to Starlight. Takes luck. Gets Mythril Sword!
	Take the Power Bangle!
Griffon: Broadsword until 14, 15 or 16 Wait value. Thunder. Repeat.
Demon: Mythril Sword spam generally works. If high Guard wait, Thunder. Opens shortcut and gets Invigorate, which is 100% essential.
	Get the Invigorate spell and the Magic Robe before these next fights.

Sylas: You want to attack twice, then block with either shield, attack once, block with "---" (the sealed action) and use Invigorate. Then slot in a Heal immediately afterwards, and survive until the second Guard by having the Broadsword and other shield sealed. At that point, you can Invigorate + Heal again and get into the following loop:
	Sealed Sword (3) + --- (5) (X health)
	Sealed Sword (17) + Heal (15) (X-23 health)
	Sealed Sword (2) + --- (5) (X+7 health)
	Sealed Sword (16) + Heal (15) (X-16 health)
	Sealed Sword (1) + --- (5) (X+14 health)
	Sealed Sword (15) + Heal (15) (X-9 health)
	Sealed Sword (0) + --- (5) (X+21 health)
	Sealed Sword (14) + --- (5) (X-2 health)
	Sealed Sword (9) + --- (5)
	Sealed Sword (4) + --- (5)
	Sealed Sword (0) + --- (1) (X-25 health)
	Sealed Sword (18) + Heal (15) (X+5 health)
Note that there's no time for damage in this loop, but there are 2 moments that progress can be made. The first is the triple --- turn, where a Mythril Sword can be used instead every other loop. The other possibility is when Sylas goes in for another Guard, at which point you can usually fit in another Invigorate, at which point you can settle into a 3x Heal loop with time to attack as well. This fight took me 8 minutes to win.

Venom: Broadsword to bait Guard. There's time to slot in a Heal if the wait is 6 or greater. Mythril Sword and Broadsword can deal damage depending on other actions- this fight was pretty basic.
Brand: Super stressful fight. You have to track Brand's Wait value meticulously and Heal every time he goes for his spell UNLESS the wait is high enough to slot in Crossbow or Mythril Sword AND a Heal before the next physical. Wooden Shield or Wing Guard to block the physical matters based on the Wait value, and Broadsword is sometimes a good move but not always. My winning fight had a ton of magic spamming from Brand, and in fact you rely on some spells being cast.

Impossible fight. If Speed Shoes were accessible, then Crossbow, Crossbow, Broadsword, Mythril Sword, Mythril Sword would deal 87 damage in a cycle. However, due to the 35 drain, this results in dealing 174 damage vs. 175 HP and comes up just short. However, Crossbow, Crossbow, Broadsword, Crossbow, Crossbow, Crossbow, Mythril Sword, Broadsword, Crossbow, Crossbow, Crossbow deals 178 damage in the same timeframe! For the sake of the challenge, either hack the Speed Shoes into inventory to bypass this fight OR make an exception and level the Heal spell for this fight only.
With 75 HP instead of 74 (eating a steak from dying) the dynamic changes slightly, but you still don't have enough damage to win in 2 cycles, even with using the Mythril Sword exclusively through one of those cycles. At best, you come up 18 damage short.

Demon Lord: I have not yet tested this fight.
