I was playing around with some skills and decided to level up my summoning doll a bit. I opened up the dolls inventory, raised his stats and then set him free. 30 seconds later his time ran out and he died. So I wait until I can resummon a new one when to my dismay the doll is the same level, but the stats are all at the level of a first level character and I don't have the option to reraise them.
Was this done on purpose? If so spending points on leveling your doll is completely worthless for a one shot deal.
