tripled spell

when cast you feel power in you grow and on your next turn you cast a spell the spell happens three times  you can target 3 different creatures if by your next turn you don't cast a spell the effect wears of and you waste a spell slot e.g fire ball happens thrice or if its not an attack spell you target 3 different creatures (cant duel spells past 5th level unless upcasted)

for every level above 5th level the spell level that can be tripled increases by 1
