For events that involve performing a specific task as quickly as possible, there should be nine trophies per event - one for which spells of any level are allowed, one for which spells of 8th level or less are allowed, one for which spells of 7th level or less are allowed, and so on. Casters would then be awarded for not only speed, but also efficiency. A particularly clever spellcaster who figures out how to beat a challenge with low-level spells before the higher-spell-level trophies are taken could sweep up multiple awards at once.
