I periodically check and greet all the NPC in all the towns just to see if they have ame new bit of trivia or added new quests. Anyways yesterday i greeted the Mage trainer in New trismus (while in mage mode) and to my suprise he offered me a prove my mettle quest which consisted of using one of my abilities and to collect some spider eyes. just for the fun i took the quest and tried to complete it. it was uncompletable by me. I coul collect the required number of undamaged eyes however because my ability was the "4" version and not he basic ability the quest would not advance. My conclusion is
1. I should never have been offered the quest as i was too high to get it
Or
2. The quest ability usage check needs to be adjusted to recognise all tier versions/skill levels of the ability
