General Strategy
To simplify things, we have color coded the teams to help players keep track of the arrows shown below.
Yellow Arrow= Team 1 Bossing team
Red Arrow = Team 2 Explosive
Turn 1

Team 1: Start by moving team 1 down towards the enemy below.
Team 2: Followed by moving team 2 to the right towards the broken tile.
Team 3: You then want to move down towards the enemy below team 3.
Turn 2

Team 1: During turn 2, it is important that you move them down 1 tile first before moving team 2 so they can swap positions.
Team 2: If you have moved team 1 correctly, they should be right above team 2, allowing you to switch positions without consuming an action. After switching positions, you then want to go towards the enemy to the right.
Team 3: Finally, move team 3 towards the broken tile to their right to set up for the next turn.
Turn 3.1

Team 1: If everything has been done correctly, the tile that team 1 is on should break and teleport them to the nearest starting tile. Move to the tile below the starting point to reach the teleporter. After teleporting, team 1 should be on the other side to end up right above team 3.
Team 2: Move 1 tile down to get closer to the boss and activate the tile to open up a pathway to the enemy to the right side.
Team 3: After teleporting team 1 on top of team 3, you will want to move upwards once to move closer to the next teleport and the next enemy.
Turn 4

Team 1: Finally, for turn 4. First, you will want to move team 1 upwards to allow team 2 to reach the boss.
Team 3: You then want to follow this up directly with team 3, teleporting them near team 2 to allow them to switch positions.
Team 2: Lastly, swap positions with team 3 and move to the empty tile below. If done correctly, all enemies should attack the teams.
320 Sec Clear

If you are aiming for a 320-second clear, you will want your team 1 to consist of AoE and Single-Target Piercing damage dealers. The second team you bring along won't matter; just move them upwards to activate the platform towards the boss, then retreat the encounter immediately. For your bossing team, you will want to just head straight for the boss. We recommend turning off Skip Battle for this.
Team Building

Team building for this stage is relatively simple and straightforward. In general, for all teams, you will want to bring a Tank, Healer, and Supporter. For team 1, you will want to bring AoE Piercing DPS. Team 2 should have a Single Target and AoE students, as this will be your main bossing team. Finally, for team 3, you will want a team full of Explosive AoE students, as all the enemies they will be fighting are Light armored.
