Has every monster that was printed with 'you not play spells with the Attack trait' been errata'd to 'Immune to the Attack trait'? Someone in our group has been sandbagging a Necklace of Fireballs in case he runs into one, since it specifies spells, not items.
Mostly just the ones that didn't require a check. So if it said "Succeed at an arcane 12 check or you may not play spells with the attack trait" that stayed pretty much the way it was. So items still work there.
Thanks. I'll make sure to mention this to him before the next game.
