Actualy elemental Sorceror gets an untyped damage bonus on thier focus spells it is weirdly worded to be: a target takes 1 damage per spell level. If The damage is bludgeoning or fire, according to your elemental type (see below). If the spell already deals that type of damage, combine it with the spell’s initial damage before determining weaknesses and resistances.
and I was trying to create an AC penalty indeed but it wouldnt work without a type. So yeah untype modifier is what I meant. i eventually added a focus spell to the creature card with an efffect of AC: -4, status because nothing else worked (at least in my test using monsters to attack each other)
