Below you will find screenshots of optimal party positioning for all 5 Challenge Reward Bosses! Please pay no mind to characters in party, gear, abilities or any other statistic. They are strictly for positioning.
#1. Sharpstone Keep:
This boss literally doesn’t matter where your people are standing, sooo I just put this here.
#2. Frostsilver Mines:
This is Optimal Positioning, if you dont stack the top two rows, your characters will get pushed back, and/or blocked by a stone wall that you have to keep killing. By stacking similar to this, you prevent a wall from being placed AND prevent knockback.
#3. Hidden Forge:
Never EVER stack, keep everyone in the same line. Unless you like fire. If boulders move you or block you from remaining in your own vertical lane, make adjustments and keep your healer alive.
#4. Harvestshield Mountain:
The lazy man’s stack If you find yourself taking many turns to kill the dragon, consider stack in the two middle lanes up near the dragon. This formation will get you a win just about everytime at low levels, at high levels, dragon is a piece of cake.
#5. Heartcoil Depths:
