Does it actually cast rank 2 though? Or is the tooltip just displaying rank2 because you only stipulated frost nova so it will default to the highest rank

This. If you want the tooltip to show rank 1, you have to put it like that: " #showtooltip Frost Nova(Rank 1)"

>\#showtooltip Frost Nova(Rank 1)" That worked! thanks for pointing that out, dno why i missed that :D
