Dark Elemental Affinity grants access to an aggro-drawing ability! Otherwise, aggro is meant to be handled more narratively, as with any other TTRPG - you might roll to goad someone, and describe how you do so, or roll to slip by someone's attention similarly.
It's been on the backburner for a while, but an expansion is still being worked on, and I'd very much like to release it eventually! Bugs and major balance issues will be fixed if they get brought up. Is there something you noticed or had in mind in particular?
