Spellcraft 3: Play Slow.
Card sounds may differ from in-game as they get updated.
Endurance - Units with Endurance ready at the start of each players turn, so they can attack and still be ready to block during the enemy turn. Additionally, they are completely immune to enemy stun and exhaust effects.
Spellcraft - When you play a weapon with Spellcraft, you may spend power to create and play the listed spell.
