Rat Swarm

Choke-point towers, upgrade order, Arthur → Marlena → Stellar investment, and Rat King burst timing in the first 10–15 seconds.

Updated:

Mode

Tower defense plus up to five heroes. Rat waves follow fixed paths toward the Rat King boss. Clearing a tier unlocks rewards and higher difficulties.

Towers

  1. Focus on 2–3 choke points, not full-map coverage.
  2. Order: damage at chokes → slow into the kill zone → AoE for breakthroughs.
  3. One maxed choke beats five weak towers.
  4. Repair before the next attempt after a fail.

Heroes

Slot Priority
1 Front Arthur (UR)
2 Front Griffith / Bella
3 Damage Marlena (UR)
4 Support Stellar (SSR)
5 Flex Claire / Bestar / Grenwald

Positions: tank front, support mid, damage rear.

Invest: Arthur → Marlena → Stellar. Spreading the roster is the main reason players stall.

Rat King

  1. Do not dump ultimates on trash — hold them for the boss.
  2. Burst Arthur and Marlena in the first 10–15 sec of the boss.
  3. Readiness: enter the boss phase with about 50%+ team HP left. Otherwise invest in the core — do not spam fails.
