the dm and i have been told by a fellow player who dm's that the fact my wizard functionally has expertise in all knowledge skills is not usable during combat at all. i can't ask him if i "know" anything, during combat. can't ask if i know about a monster. know any of its vulnerabilities. commonly known weaknesses. rarely known ones. i have a +12 to all knowledges. i can't ask to know any sort of thing about combat? really? is there anything about this that isn't quite right? he's been told he shouldn't ask me to roll any knowledges at all when i see a creature. basically this player in and out of combat keeps finding reasons to say knowledge skills basically just don't have functions.
