This needs to be fix, impossible to play summoner in multiplayer. Reloading the game causes skills to disappear from bar and there's no way to add skills to the pet bar.
You can add the skills to summoned allies provided you mash the 'K' key just as your character ends their turn before it switches to the summoned ally. Also have the skill panel open before the incarnates turn and after the character's if they are further down the initiative order will switch to the incarnates skill panel when it gets to them.
