Minimalist
Reach wave 35 using at most 2 distinct tower types.
The word that catches people out is "distinct". Twenty Radiance path A towers are one type. A type is a school plus a path — Radiance A and Radiance B are two different types. And the game counts every type you have ever built this game, not the ones standing now, so selling a mistake does not undo it. One stray third tower ends the attempt for the whole run.
The two to take
Radiance path A (the path is itself named Radiance), and Chronomancy path A (Stasis). The pairing is not arbitrary:
- Radiance is the only school that can shoot a stealthed enemy. Stealthed enemies can appear from wave 20. Radiance targets and reveals them, letting the rest of the line fire too; splash damage can still hit hidden enemies.
- Their combo stops enemies. Radiance + Chronomancy is Eternal Vigil: its combo stuns the target for 2 seconds. Its advertised tower-speed buff has no effect in this version. Side-by-side towers separately gain +3.2% attack speed and +0.5 range.
- Radiance A brings area damage and support; Chronomancy A brings the crowd control that a two-type defence has no other source of.
The run, in order
Expect it to be tight. The recorded run was down to 9 lives by wave 4 and held on at 8 from wave 10 until wave 35.
The recorded run
One game on a fresh profile on Wanderer's Waypoint, played by the game's built-in AI limited to these two builds, through the game's normal mouse and keyboard at a person's pace; your enemy draw will differ. When wave 35 cleared it had 83 towers and 504 combos on the counter. It cleared wave 36 and ran out of lives in wave 37, ending on 86 towers, 726 kills and 589 synergy combos, with exactly two tower types on the board the whole way.

What breaks it
- A third type, ever, at any point in the run — including one you sold.
- Dying in wave 35 rather than clearing it.
