Ok so my Cu is 100 in all skills but healing, he was stuck at 93.3. I had been trying to raise his healing on rotting corpses, but nothing. In desperation, I tamed a unicorn and released it in my house, making sure that it was separated from where my Cu was going to be. In the last 7 hours my Cu has gained 5.0 healing, not the greatest gains, but beats being stuck at 93.3. Oh I also discorded the Cu. Oh the Unicorn doesn't seem to have gained any skill but meditation, which is 100 and it has 136 dex, which is higher then I could ever get it by training it. Too bad it isn't a keeper.
