A few small balance and modding changes to the beta:
Modding:
Game now checks that all elements of the spell list are actually spells before launch (ah typ)
A few balance changes:
Mercurize
Initial max charges 8->6
Lightnign Spire
Now the arcs hit cells adjacent to the targets as well as along the beam (hopefully less awkward to actually deal damage with this now)
Other balance:
Gold Drake
Dragon Mage upgrade cost 6->4 cooldown 15->8
