I have no clue what this message is for, it just stated happening one day when I was zoning. and now it happens often. What do I need to do to fix it? thanks!
I have had that issue myself and it just seemed to go away after a number of character levels. It seemed to start after picking one of my Necromancer Level training spells.
I'm* seeing something similar. 'Must be non-fighter to equip' (from memory) in red text, which makes no sense to me. I would suggest using /bug to report it. * [cough] not really me [/cough]
If i were to guess it would be that you used a book to learn something like Undead Knight II Expert and then chose the level 14 Grandmaster training. **this is just a thought neither may be a real thing** I'm guessing the combination of a book and training will cause that until you get the next level of the spell. Wild guess though. But ya /bug it?
