The Hidden Forest

When under the feedback effect for Gelid strike Rk.III, spells cost much more mana. It doesn't seem to be set in stone. I'm seeing Chaotic Detonation take anywhere from 6k-11k mana to cast while under that effect. Not limited to fire and does the same thing with flare/bloodmage active or not.

Thanks for reporting it, added to the internal bug list to investigate.
