Sure if you read fine print on warscroll packs it says you need battle tome.
I’m sticking with just Malign Sorcery. The faction specific spells cost twice as much.
No justification for one hero costing more than a unit.
I’m only playing friendly games, so I’ll be using proxy from my RPG, boardgame and wargame selection for heroes and wizards.
Don’t forget… all warscrolls are free pdf.
