I actually managed to do the jump from the edge without activating the button - just don't ask after how many tries! lol
Anyway, on the second go through FoV I decided to reset my skills and maxed Mindread even before starting any quest. Result? All Mindreading costs 0 XP... no more XP debt!
You know, I only ever trained my Mindread skill up to level 3 or 4. Know why? There's so much experience available in the game, it doesn't make much sense to burn limited skill points to save on essentially unlimited experience points. So, I have to run another quest or two, or kill a few more enemies. I still level up fine. Particularly in FoV, where you have unlimited re-spawns of undead enemies that give you 3000-5000 experience *each*. (I can see in the original Ego Draconis, training up Mindread higher, so you level higher by the end of the game, but in FoV there is seriously very little benefit to saving a few hundred thousand experience).
I'd rather have a skill that's very useful trained to a high level - like healing, defensive posture, a special attack/spell, Way of the $Archtype, a nice support skill like Mana Efficiency, Potion Efficiency, etc.
