aural decoy is low investment at least! 3 levels at most from any class. (most need the int, some also need levels in attunement to actually get a spell slot).

dont wanna backseat too hard though!! ^^

Capra is one of those infamous fights that I look forwards to every replay. Felt ball-busting my first go around but there are some surprising workarounds.

Aural decoy works on all 3 of them! And for the low low cost of 10 intelligence.
Just...cast it at a wall to have it work better lol.
