Dossier Summary
Skill loadout
8 AbilitiesEvery skill REX can equip, with the slot it occupies, its cooldown and its proc coefficient. Skills listed as alternates replace the default for that slot and are unlocked through the challenges underneath.
| Skill | Slot | Cooldown | Proc | Availability |
|---|---|---|---|---|
| DIRECTIVE: InjectA three-shot burst where each shot rolls critical chance separately, fired in a narrow horizontal fan that makes landing all three at long range unreliable. | Primary | — | 0.5 x 3 | Default |
| DIRECTIVE: DrillHits sixteen times across three seconds, giving REX its heaviest single-target damage. | Secondary | 6s | 0.5 x 16 | Default |
| Seed BarrageA rapid secondary on a half-second cooldown at a full 1.0 proc coefficient. | Secondary | 0.5s | 1.0 | Alternate |
| DIRECTIVE: DisperseKnocks enemies away, with larger targets pushed less, at a zero proc coefficient so its damage will not drive on-hit items. Used in the air it pushes you back toward the camera. | Utility | 5.5s | 0.0 | Default |
| Bramble VolleyHeals a share of maximum health for every target hit while knocking them back, again with less effect on larger enemies. | Utility | 5.5s | 0.5 | Alternate |
| DIRECTIVE: HarvestInflicts Fruiting for ten seconds. Killing an affected enemy drops two to eight fruits scaled to that enemy's maximum health, and the attack has a small radius so several enemies can be marked at once. | Special | 6s | 1.0 | Default |
| Tangling GrowthPlants a flower that unfurls over a second and lasts eight seconds. Its ring roots and drags in enemies, and REX heals each second per snared target, including from enemies killed inside it. | Special | 12s | Projectile: 1.0 <br>Roots: 0.0 | Alternate |
| Natural ToxinsInflicts an armour debuff lasting three seconds. The in-game text says 20 armour; the actual figure is 30. | Passive | — | — | Default |
The proc coefficient scales how strongly on-hit item effects trigger from that skill's damage. Reported by players — Compiled from player reports and community guides; confirm in your own run.

Reading the loadout
REX carries 8 skills across 5 slots (Primary, Secondary ×2, Utility ×2, Special ×2, Passive). 3 of them are alternates rather than a default pick, which puts a real choice in the Secondary, Utility, Special slots.
- Cooldown range
- Shortest is 0.5s on Seed Barrage; longest is 12s on Tangling Growth. That spread sets how often the kit can answer a problem rather than absorb one.
- Proc profile
- Highest proc coefficient is 1.0 on Seed Barrage, DIRECTIVE: Harvest. The primary sits at 0.5. 1 skill carries a coefficient of 0.0, so it does not trigger on-hit item effects at all.
- Unlock work
- 3 challenges are tied to this survivor, listed underneath. Clearing them is what opens the alternates rather than the character itself.
The kit splits into 3 slots built around dealing damage and 4 slots built around repositioning or burst windows. The primary's proc coefficient of 0.5 means it triggers on-hit item effects less reliably than a full-strength hit, so builds leaning on proc items will want another source. Note that DIRECTIVE: Disperse carries a coefficient of zero, so damage from that skill will not drive on-hit items at all.
This breakdown is computed from the table above rather than quoted from a guide, so it moves automatically whenever a listed value changes.
Origin and version history
- REX has been on the roster since the base game, which puts the character inside the balance pass that patch 1.21 was written for.
- Patch 1.21 added Proliferation (Utility) as a new option for this kit — one of six original survivors that gained a skill in the free half of the Hallowed Concepts release.
- Hallowed Concepts also shipped a skin for REX, so the most recent cosmetic change and any mechanical change to this character came from the same release.
