Fast. Play after your turn begins.

Disengage from each enemy engaged with you. Until the end of the round, enemies cannot engage you and you cannot deal damage to enemies.

Aw. Trish got Ethereal Form!! Only at 0 cost and better icons, but really. It's Ethereal Form. Anyway, I know you like Trish, so let's not be too particular, but it's Ethereal Form. Trish gets to disengage. move around, and not interact with anyone. That, as you may have noticed, is Ethereal Form.

While it says that enemies can engage you, does that also mean trish can't engage enemies? I'm thinking of a niche case where she plays this, engages an enemy, and then moved that enemy to another location with her. — jdk5143 · 1
Engagement is mutual. Trish cannot engage enemies after she has played this. — toastsushi · 62
Ethereal Form takes an action *and* a skill test. I don't see people calling Working a Hunch a basic investigate action... — Thatwasademo · 30
