Forum:How to get extra skill points

Me and my cousin found this out last night on accident while we were playing the underdome, He was going to take me through all the arenas on my lower lever character while he was 50 so i can hurry and get my skill point and we didn't relize this but he already had an extra point from beating them before and since he was playing with me as leader he got the quest again and once we finished it and turned it in he got an extra skill point, so now he has 2 extras. We played this on ps3 on co-op incase you try this under other conditions and it doesn't work.
