Build Tips
Your next DPS target once Skeleton Archer is maxed. Burn Patch ignites up to 4 enemies and Burning Wound adds damage over time on hit. Weak as a first investment because the Archer is far cheaper to bring online.

Ranged Tips
- Keep ranged units behind guards with separation so heroes cannot jump past the frontline.
- High Range units (15+) can sit safely at the back — prioritize Cursed or Demonic rolls on your main DPS pick.
- Skeleton Archer at 1 Soul is the best early ranged value; save Souls for mutation rolls on A-tier units later.

Passive ignites enemies with burn DoT over several seconds; strong vs grouped heroes, pairs well with other AoE units
Unit FAQ
Do mutations change this unit's abilities?
No. Mutations only multiply ATK and HP — active abilities, passives, and Range stay the same. A Cursed or Demonic copy hits harder and survives longer but keeps the same skill set. See the mutation variant table above for exact numbers.
What does population Cost mean on the unit card?
Population Cost is the number of slots this minion consumes when deployed. Your total slots come from Skill Tree nodes like Population I and II. A two-slot support like Cursed Acolyte needs Population II unlocked before you can field it.
When should I spend Souls on this unit?
Spend Souls on units already in your active layout — not bench picks. Cheap starters (1–10 Souls) are fine to buy directly. For expensive units, batch mutation rolls during Cursed Moon when odds double, and compare DPS per population Cost in the Unit Value Calculator before committing.
