Yeah, there is no real held action just a ready action, and it is real specific and would be hard to code. But maybe heal if Gale drops to 0 HP. Attack after this character. Attack after this enemy moves, or after you are attacked. Maybe like 5 scenarios. BG2 had contingency spells and we are in 2020.
I see what you mean and I totally forgot the contingency spell! also you are right it's supposed to be ready action so i updated the thread title.
