Completed the entire game. All the fairies and all the pixies have been collected. You just need to go through the ending, go down into the dark cathedral and beat the guard. (Take Ocean with you - all the necessary spells are worth it). The best fairies in the game are level 60 and 59 with all the spells - play with them. Skelrath level 49 and everyone below in level. Purely for the collection :).
