ok solod colkhab today on geo, and used various times geo 2 hour with acumen and malaise, bumping tier IV nukes from 4k~ to 10k~+ nukes and my blizzard 1 nukes from 1700 to 5k~ (mind you was useing seidr cotehardie), i dont even have idris so i cant imagine how powerfull this becomes with idris, first time used this i had a wtf moment.
just put cor + geo into a pt wiht blm and watch them nuke tier 1 nukes for 10k dmg ¬.¬
