Subtractem's 3.18 League Start Strats

Heist
  - Infinite Heist incredible early strat PoM guide: https://www.youtube.com/watch?v=OLs7HAtg-vs
  - Good later on, supply of contracts/markers might be weird if people take "no heist" node on Atlas (which they shouldn't, it's LOTS of free money if you're willing to sell in bulk on TFT, will be worth EVEN MORE if people take that node)
  - You usually love it or hate it, but it's incredibly good

Harvest
  - good always
  - reforge cluster jewels early and often
  - buy Sacred Blossom asap to get much more value each harvest
  - look up guides by SpicySushi for advanced big strats
  - HC players beware rippy

Betrayal
RECOMBINATOR!!!!!!!!!!!!!!
  - Veiled items / selling crafts (-mana cost, trigger) are valuable first 2-5 days
  - good passive currency going if sell on TFT
  - monitor scarab price for Intervention, we don't know economy yet
  - gets WAY better a month into the league (Aisling 3ex+ each)
  - Guide: https://www.youtube.com/watch?v=Rox_0WRqjCg
  - HC players beware rippy

Delve
  - Great early if you know what to look for (curse rings, minion items)
  but generally not the best unless you're competent and dedicated
  - Usually just used to get safe XP at the end of a level
  - Actually bad for fossils, only good for resonators when deeper

Expedition
  - Top tier always, Rog Tujen and Gwennen all good for different reasons
  - Even if you just sell reroll currency and logbooks you'll make bank
  - Just watch the guide: https://www.youtube.com/watch?v=KcZZ-9OJZS4

Blight
  - Really good if you have the right build
  - Top oils sell incredibly well
  - Blighted maps can easily net you 1-3ex each when rolled properly
  - Friend made 2 mirrors doing Blight early for a week last league
  - Even BETTER this league because of Shadow Shaping (up to +12% chance for Kirac implicit -> Blight encounter maps)

Metamorph
 - VERY good early, especially since so few people usually do it
 - Have to fiddle around with organs, can be annoying
 - Palsteron guide: https://www.youtube.com/watch?v=IkTv_7GEXGQ
 - HC PLAYERS BEWARE RIPPPY

Bestiary
 - Can be good if you FULLY invest into it (all bestiary points on atlas tree)
 - You're fighting multi-boxers/macro users for profits
 - Supply/Demand very fragile
 - Really annoying to interact with

Incursion
  - Good early if you go for incursion mod items (ele or trap/mine gloves)
  - Gets WAY better later when folks want to double corrupt things (2ex per temple, super easy farming)
  - Usually just used for Delirium juice initially

Breach
  - Kind of bad, really just Deli juice
  - Monitor breachstone prices, ok passive income sometimes but been bad as pure profit strat for a while now

Synthesis
  - Pretty bad in 3.17 BUT...
  - Recombinator MIGHT us salvage good synth implicits on bad bases!
  - Uber Cortex maybe has more value now also

Harbinger
  - Just really good, might not feel super impactful per map but easily
  will end up netting you dozens of exalts passively. The shards really do add up. Monitor Ancient Orb price.
  - Also great Delirium juice

Legion
  - Traditionally quite good, even when Emblems sell poorly it's great map juice and the Legion mobs drop a ton of good loot from many other league mechanics
  - Rippy as hell, HC players beware

Delirum
  - Deli maps are the biggest juiced farming in the game currently. This likely wont change. If you like doing it, consider Deli maps early
  - On map device, at high investment the >10c per is a drop in the bucket
  - Combos with nearly every other strat in the game
  - Simulacrum is one of the most profitable things in the game...if your build can handle it and you enjoy doing it
  - It's just SO grey

Essences
  - Really good, either for crafting or selling in bulk.
  - EASY early crafting for profit, especially with Omni meta
  - Even if the price dips, HODL. There was panic selling this league and it turned out to be silly, it super bounced back with Omni going meta and this should stay true.
  - Even better on map device

Strongboxes / Ambush
  - it's just free real estate, balance it with opportunity cost

Shrines / Domination
  - Baby headhunter, lets you farm VERY quickly and safely

Ritual
  - Very hit or miss. Can be ok if you go all in on it but 99% of the time will be pretty bad and just worse than something like Expedition
  - Usually just nice Deli juice
  - Might interact with Sentinel in an interesting way?

Beyond
  - Deli Juice

Abyss
  - Good Deli Juice
  - jewels and belts good money early, drops off quickly
  - great xp with atlas nodes

Bossing
  - This is a super general topic. The short answer right now is: we just don't know. Based on drop rates (Omni/Ashes) this could vary a LOT. 3.17 was supposed to be a bossing league and it turned out...not to be. Based on trailer/teaser knowledge Bossing looks good but don't jump the gun.

Rogue Exiles / Torment
  - exiles are good for SSF/early rares
  - No

Kirac Missions / Scouting Reports
  - YES
