Larian Studios Forums Baldur's Gate III Baldur's Gate III - General WTF is the Hag encounter? [SPOILER]

The problem is, the first thing I tried to do with the copies were exactly the magic missiles. I thought that one hit should suffice killing an illusion.
I was wrong. I don't know if this is a bug or what but it took me like 15-20dmg to take down a copy.

EDIT: pf course I burst her with stealth Astarion but again, as soon as she summons the copies they have the initiative and hold-person my entire party.
