It´s level 15 frostbite already not 25, it´s max rank is 3. But to be honest? Frostbite itself is pretty low on Icicle spear, Fumiga, Miu(well miu might be fine actually). Like when you compare it to cincer tiles which also deal damage at start of turn and don´t "use" the tile it feels a bit lackluster in comparsation, but yeah I can see that it would be unfair to those skills I guess.

So I was hoping to slighty increase their levels later on, since cinder usually does more damage and does that damage more reliable, without a buff attached to it, and can be pushed back and forth on those tiles. And barely anyone even moves over ice tiles nowadays on their own(It´s still great for PvE), cause of movements skills.

I guess damage can be reduced a little but I was looking at splash while comparing it, which has tons of utility and also does more damage on a fully defensive stat and it being magic can also be a huge advantage cause you know.... Spellthief. But I do not mind either the ice atk being reduced or the effect put down to lv10 frostbite.
50% ice atk doesn´t sound bad actually for a 1M tap, making it still pretty decent.
