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

Team 1 and Team 2: Move both teams closer to the boss by taking the tile to their right side.
Turn 2

Team 1: Start out turn 2 with team 1 by moving them to the tile towards the upper right.
Team 2: You then want to swap positions with team 1 to move to the tile right behind the boss this deactivates the tile team 1 is currently positioned in and teleports them back.
Turn 3

Team 2: For turn 3, you’ll want to start with team 2 to activate the tile to the left of team 1.
Team 1: Move towards the newly activated tile on the left side.
Turn 4

Team 2: Once again start this turn with team 2 and move them towards the teleporter.
Team 1: Swap positions with team 2 to reach the boss.
120 Sec Clear

For a 120s clear, you will not need a 2nd team so we recommend only having 1 team. Follow the arrows as shown in the image above to get a 120 second clear.
Team Building

Thankfully, team building for challenge stage 2 is simple and requires only 1 team to do all the fighting. Team 2 will mainly be there to activate step tiles for team 1 to reach the boss. Since team 1 will have to do both mobs and the boss fight, we highly recommend bringing a good mix of AoE and Single-Target damage dealers to have an easier time.
