Imagine my surprise (and disappointment) when, after dumping tons O points into Upgrade Summon Doll, I could not untrain it.

Since I "knew" I could untrain any skill (for a price), I thought I'd experiment with the level of the summoned being and re-assign the skill points later while still making progress in the game.

Since that time I've put in tens of hours of game play and would like to get those skill points back.

Do I have to lose all that time and (hopefully) find an old save game before the Upgrade Summon Doll skill was increased? OR do I just have to chalk it up to experience (no pun intended).
