Slotbound Outlaw build: cavalry evolution route to level 12

Pick a cavalry unit in the first waves and absorb every other unit you roll into it until it reaches level 12 and evolves into the Outlaw Cavalry. Both players who documented this route on YouTube describe it as the run-carrying strategy: one calls the outlaws the units that "absolutely carried me through this run," and the other finished the demo behind a level 12 Outlaw Cavalry. This is based on demo play (v0.4.x); the official Steam page has Slotbound launching in Early Access on November 10, 2026, so numbers may shift.

How the evolution line works

Cavalry evolves in stages as you feed units into it via absorb:

1. Level 6: Axe Cavalry

   One player reports the first evolution triggers at level 6; with enough absorbs the horse gains a damage-heavy evolution and starts "absolutely cleaning up" waves.

2. Level 12: Outlaw Cavalry

   The second player pushed to level 12 and got the Outlaw Cavalry, whose final-tier ability was one kill restoring 5% of max HP, plus an attack that consumes 15% HP to deal 220% damage to up to three enemies ahead.

3. Stop there

   Both players treat the Outlaw as the final evolution in the demo — it cannot evolve further.

Building the run around it

• Keep one or two warriors in front of the cavalry so they soak hits while it attacks from behind.
• Roll and nudge aggressively for more horse symbols, and spray any spare unit into the horses as absorb fodder — one player kept feeding "whatever" just to push levels.
• In the shop, buy damage, health and armor for the team; neither player found cavalry-specific items, so take what helps.
• Absorb when the machine shakes — it is the way to make board space and refunds some money.

One caution: the absorbed-unit ability rolls appear randomized, and the second player says he could not tell whether the units you feed influence the result. Meta progression (extra board slots, item slots, cheaper rolls) makes feeding easier on later runs.

Community build guides list Veil tank and Necro Lord carries as the other demo archetypes, but this cavalry route is the one the Outlaw name belongs to.

FAQ

Yes — the players who recorded it ran the tutorial and Normal difficulty in the demo and cleared wave 10, though the boss fights stayed close.

Check note: evolution levels and abilities come from two first-hand YouTube playthroughs (video one, video two); the Early Access date of November 10, 2026 comes from the official Steam page. Exact evolution thresholds are player observations and unconfirmed by the developer.
