Entangling Heat Force Upgrade

Normally, I'd wait for a few upgrades before doing this, but I think I'll need every bit of damage I can muster for the event.

Entangling Heat Force: (20Wood, 40Fire, 2TC) -> (30Wood, 40Fire, 3TC)
W/e floats the boat.

Further upgrading. If my math is right, 95 cap, 10 free damage.

Entangling Heat Force: (30Wood, 40Fire, 3TC) -> (40Wood, 50Fire, 3TC)
metal, approved
Reopened for new Upgrades!
