Small update from us to slightly adjust some things that got a little too overpowered with our latest update.
Reduced the default frostfire slow effect on ice enchanted fire towers to 15% (down from 40%).
Burn stacking now starts at 10% (down from 15%).
Added one more level to the "Stacked Heat" (increased burn stacking) upgrade.
Fixed an issue with the level 3 build challenge where overkill damage was accounted for when it shouldn't be.
