To give a spore raised creature its own full size portrait, have it enter combat by itself, then use a door with the character it is attached to. If Gekh Coal has his own full portrait, every creature he raises will get a half portrait, going to camp will recharge his spell slots and also turn raised corpses back to their original form.
