Hussar
Legend
Each player *other than the caster* runs one or two of the conjured animals, determining their actions and rolling as needed, immediately after their character's turn.
This way, the spell accomplishes the *character's* goal, but does not give the caster's *player* all the spotlight and table time.
Not a bad idea. Depends on how many critters he's summoning I suppose. Typically, it's probably going to be 1, 2 or 4, by and large. Not too many more than that and 2 seems to be a pretty decent compromise. On the plus side, it's pretty fast to run most animals - one, maybe two attacks and that's about it. It's not like in previous editions where summonings could get seriously out of hand.
