General Strategy

Use AoE and Ranged Units in the Left Flank

For the first wave, Flying units will all be coming from the left pathway, so be sure to put either the Suppression Specialist Mek or Bubbler Seahorse near the left path.

Place Units Between the Paths for Waves 2 and 3

For Wave 2, only the Center Flank will have enemies, and Wave 3 will only use the Left Flank. To get the most use out of your units, place them in between the pathways so that their range can cover both flanks!

Use Leadership Skills to Heal and Apply Hydro

The Leadership Skill for this round heals your units and deals Hydro DMG in a small AoE. Use it to keep your units alive and help with Elemental Reactions!

Event Information

Stage Information

The playable stage consists of a circle where the player's base is, and is connected to two paths on the left and in front of the base.
