Campaign and Sky Tower Boss Guide 2026
A practical Archero 2 framework for Campaign and Sky Tower bosses: patterns, chokepoints, skill drafting, movement, and progression builds.
By the CAPPED Editorial Team · How we review guides
Quick answer
Campaign and Sky Tower boss progress is primarily a pattern problem. Learn the attack cycle first, then choose a weapon and skill page that can attack safely inside those windows; do not assume a set name solves every floor.
Campaign patterns
- Stone Golem: use the wall to cancel boulders when the arena permits it, stay close, and rotate counter-clockwise.
- Scythe Mage: keep distance, limit movement, and use the gap between the first and second scythe sets to answer the third.
- Flame Demon: follow a triangle route and a shoot-shoot-move rhythm.
- Flame Dragon: stay close, make small sidesteps for the center fireball, and remove summoned elite dragons when your damage cannot ignore them.
Sky Tower checkpoints
- Floor 349 Imp: dodge the first random meteor immediately; the second attack becomes a readable diagonal row or cluster.
- Floor 350 Summoner: prioritize survival and attack after the four-arrow cycle.
- Floors 347-348 Red Crab: move vertically above or below the crab and attack during its bounce window.
- Red Turtle: use the bottom-left safety position for the relevant encounter.
Additional pattern notes
- Medusa (formerly Whirlwind Monster): stay close to the selected short wall and read the undulating projectile lane.
- Tomb Keeper: play one side of the map, leave red markers before impact, and distinguish the fast and slow meteor splits.
- Bosses can one-shot progression builds, so dodging and pattern recognition may matter more than adding another HP upgrade.
Movement rule
Move for a reason: leave the telegraph, create a clean projectile lane, or reset range. Constant panic movement lowers damage and can steer the boss into a worse position.
