I found another glitch. I used Arcane Energies to turn all attacks from heroes equipped with weapons into Magic Attacks. It only applied to one hero instead of all.
There's a glitch I found. I use Magical Aura to change weight to 0, then draw a card. Then, if the card I draw is a weapon, that weapon is not Weight 0 as it should be.
