ToME: the Tales of Maj'Eyal

To make a long story short, 1 point in Combat Accuracy had slipped by while I wasn't paying attention and is now non-unlearnable (double negative, yay). Not a big deal, I know, but I'm very anal about those things and It's pretty much a thorn in my sight.
Is there a way to unlearn it now, like and addon or a "trainer" or something, getting a Ghoul Marauder out of NM Starter dungeon again would be a real pain in the ass.

There are several addons which can allow for full respeccing, but applying one to an existing character doesn't seem to work quite right. You can unlearn anything, except what was already unlearnable before you applied the addon. I had a similar problem with a misplaced point in a completely un-unlearnable talent, but it was early enough in the run that I just went ahead and restarted.

Unless someone knows an alternative method (save editing, maybe?) then you might be stuck with whatever you mistakenly learned.

Yup, I'm pretty early myself, only level 5, but getting the ghoul bugger out of the Blighted Ruins took like 50 tries, and to add insult to injury I even managed to kill the Bone Giant, while the plan was to hit the stairs ASAP.

Why do you want to unlearn it in the first place? A marauder has a lot of use for combat accuracy.
