Copy Experience spell in Enchanter base list Seeming Memories has rather unclear limitation, which does not much make sense. I have seen some rulings in the net but those do really answer much.
So if caster gets 1% of experience of target per round, that would be minimum of 100 xp per round (for level 1 target). But is maximum is level times 10, the maximum would be 10 xp for level 1 target. What is the point of having multiple round duration anyway? As has been pointed out, casting the spell would gain more xp just be itself, if the maximum is so low.
