Looking over the info of this update, All r/e/m/e weapons for mages got a boost to magic damage, and several got a boost to MAB and MACC (laevateinn got 10 mab and 20 macc)
Claustrum even inexplicably got +60 accuracy to avatars...
Yet Nirvana received no change at all to avatar level or bloodpact damage. The new staff has no difference to avatar damage output at all compared to the damage output of all other mage staves for their nuking capability.
