I had an issue with Jake getting hit by lingering AoE ground effects after my battles.
So I position my party around the corner on the stairs, have one member sneak down the right side to be within range and drop a single target high damage skill on her.
(This party member should NOT be linked)
I then run behind cover, skip everyone's turn and unload on the summons et all once they round the bend. Trivializes the fight really, and no risk of death to Jake. (well second death)
