Enemies spawn in waves and follow set path patterns. Knowing the path runner mix, open-world clusters, and floor-locked bosses is the difference between a clean clear and a full reset before Wave 25.
Path Villains are the standard wave mobs. They spawn in groups and rush lanes. Use AOE units (Quake, Luffy with AoE traits) to clear efficiently.
Open World Mobs on Jotunheim Island are the only source of Sky Keys. They drop at 100% per kill, so dedicated farmers should run 2-3 loops before pushing Sky Spire.
Tanky Bruisers appear in mid waves. They eat a lot of base HP if your single-target units cannot burst them down. Counter with Corrupted-trait or Void Emperor-trait carries.
Splitter Mobs split into smaller units on death. Counter with units that have a strong AoE finisher (Yamamoto Secret, Luffy Gear Second).
Shielded Mobs have a temporary damage reduction buff. Counter with high cooldown reduction traits (Corrupted, Void Emperor) so your top carry can re-apply damage quickly.
Speedsters outrun standard carries. Counter with units that apply AoE debuffs on lane contact. Most relevant for the Wave 1 to Wave 25 no-checkpoint window.
Regenerators recover HP between hits. Counter with high DPS windows (Corrupted trait) so each hit removes more HP than they regen.
Boss-wave minions spawn alongside boss units. Always clear adds first or the boss regen / buff effects snowball. Use a fast AoE opener before engaging the boss body.
