I was just testing with Wilhelm, and with the combination of spells, and items, he should be able to get his lore to a base of 88, but it maxes out at 75. Is there a hard coded limit to the skills, or is there simply a limit to how far from the base skill level it can be buffed up?
It's not really worth me putting anymore points into it when he levels again, and especially not in throwing a skill focus into it, if the skill will never go up from what it's already able to reach. Would it be possible for a DM or Dev to test this to see which it is?
Edit:
Nevermind. I quickly tested it in single player and got the lore to 127. It's a limit to the buff, not the final number.
