The ones worth planning for
- One Clean Throw — the spearis throwable from the first shop visit. Y'm-bhi walk in straight lines when they've locked a target; let one commit, then throw at the head.
- Like Moths to a Flame — the Jar of Black Ichor costs 10c. Find a spawner-dense area, plant it, and step well back; the five creatures it pulls do not need to survive the experience.
- Long Shot — the Bandurria drains sanity passively, which is exactly why you want the 50-meter kill: the achievement rewards what you should be doing anyway. Longbow or musket both reach.
- The revive chain (10 / 30 / 50) — take Ammonia Saltson every run and be the crew's medic; it stacks across expeditions.
- Too Stubborn to Die — the long revive grind. Favors Basic contracts and quiet loadouts: greed is the enemy, so take the small haul and walk out with the crew intact rather than chasing one more shrine.

Achievement questions
How many achievements does The Mound have?
25 on Steam and Xbox, spanning rank milestones, contract tiers, revive counts, combat feats and collection sets. PlayStation lists 26 because it adds a platinum trophy for earning all the others.
What's the hardest achievement in The Mound?
Too Stubborn to Die (50 revives) is the longest grind, and the full collection sets — Nine Guardians, The Horrors Named, The Full Account — are the ones that outlast a casual playthrough. Tempered by Madness (rank 30) is the headline climb.
Do demo achievements carry to the full game?
The developers have said demo progress carries over (while recommending a fresh start to see the held-back content). Whether that includes achievement pops specifically hasn't been detailed — we verify on launch day.
