So Deathjack has spells on his card but as far as I can tell doesn’t have any rules that allows him to actually cast the spells via anything except Necrotheurgy.
Spellcaster is on warlocks/warcasters/infernal masters and animus explains how they can spend fury to cast animus.
Can deathjack only cast one spell per turn via Necrotheurgy or can he spend focus to cast a possible second spell.
