Who tanks, who hits, who eats two slots. Check Unit Index in-game for real stats.

Roles and stages — not a letter tier list. Names and costs live in the in-game Unit Index; if ours disagree, trust the Index.
Unit index

| Iron SkeletonUsual first upgrade off Bone Grunt | Frontline tank | Early | 1 |
| Skeleton ArcherPark behind a melee | Ranged backline | Early | 1 |
| Shiny Skeleton ArcherSame job as Archer — keep it off tile one | Ranged backline (Shiny) | Early | 1 |
| Imp BomberTwo slots — place behind melee; good when packs clump | Backline AOE | Open | 2 |
| Shiny Lava ImpUsual first post-25 upgrade | Backline carry (burn) | Wave 25+ | 1 |
| Bone GuardThick melee after Wave 25 — buy Population before stacking these | Melee tank | Wave 25+ | 2 |
| Blood GargoyleAlso labeled Bloody Gargoyle. Frontline for Wave 50–75 with Lava Imps behind | Frontline carry | Wave 25–75 | 1 |
| Grave WarlockOnly after the frontline is solid | Backline damage | Mid | 1 |
| NecromancerFinish a basic melee + ranged core first | High-cost tool | Mid–late | 1 |

| Shiny DeathlockSpawns skeletons — dies fast if left exposed | Skeleton summoner | Late | 1 |
| Demon ButcherLate damage once Barbarians / soft support stop carrying | Late DPS | Wave 125 | 1 |
| Mighty OrcSafe Fusion Shard dump when you pull one — check kit in Unit Index | Mythic frontline / carry | Mid–late | 1 |
| Great WarlockMay overlap naming with Grave Warlock — confirm in Unit Index | High damage | Mid–late | 2 |
| Cursed AcolyteWorth the slots when Population is up | Passive support | Mid–late | 2 |
| DoomfistOn the Roblox page — kit still needs a Unit Index check | UPD2 unit | Update 2 | 1 |
Early formation
Usual open-game shape before Wave 25. Swap when your wipe shows the hole.
| Position | Unit | Why |
|---|---|---|
| Front line | Iron Skeleton | Soaks first contact so the backline isn’t deleted |
| Extra melee | Bone Grunt | Cheap second body while Population is low |
| Ranged | Skeleton Archer | Steady damage from safety |
| AOE | Imp Bomber | Clears clumps when single-target falls behind |
| Flex | Grave Warlock | Only after the four above aren’t starving for slots / Souls |
Checkpoint swaps
Replace the old core when the next checkpoint stops moving.
| Checkpoint | Focus | Note |
|---|---|---|
| Open → Wave 25 | Iron Skeleton + Archer + Imp Bomber | Force Wave 25 even if the boss cleans the last heroes |
| Wave 25+ | Shiny Lava Imp + Bone Guard | Drop tutorial imps; Population before stacking dual-slot |
| Wave 50–75 | Blood Gargoyle front, Lava Imp back | Boss weapon matters more once elites survive the first clash |
| ~Wave 100 | Shiny Barbarian; test Soul Collector | Cut support that doesn’t hold |
| Wave 125 push | Demon Butcher core | Keep support only if it still moves the checkpoint |
Formation tips
- Tanks in front, damage in back. Glass on tile one is how you leak.
- Dual-slot units (Imp Bomber, Bone Guard, Great Warlock, Cursed Acolyte) eat Population — upgrade slots first.
- Passives beat Power rating — burn / AOE / marks often outvalue a slightly higher Power filler.
- A mutated Bone Grunt can still beat a fresh Iron Skeleton for a while — mutations juice ATK/HP, not the role.
- After Wave 25, one thick tank + a mutated backline beats a pile of tutorial trash.
- If normal waves leak → Population / Unit Damage. If only bosses wipe you → weapon / Boss Attack.
- Dump Fusion Shards into units you actually field.
- Update 1 added three units that still aren’t consistently named outside Unit Index.
Mutations
Mutations only change ATK/HP — kit stays the same. Full table on Mutations.
Quick path
- Early: Iron Skeleton up front, Skeleton Archer behind, Imp Bomber when packs clump.
- Wave 25 → Lava Imp + Bone Guard → Gargoyle → Barbarian → Demon Butcher. Dual-slot only after Population.
- Doomfist is UPD2 — kit still needs Unit Index.
- Spend order → beginner guide.
FAQ
Minion vs unit?
Same thing. Players say minion; Unit Index and update notes say unit.
Where do units come from?
Mostly the Altar with Souls. Mutations can roll on summon. Open Unit Index for names and costs.
What’s dual-slot?
Unit costs two Population. Stack those too early and you can’t place anything else.
Is Doomfist real?
Yes — Update 2 lists it on the Roblox page. Exact kit still needs a Unit Index check.
