So maybe I'm misunderstanding how it works:
supposed to add 1d6 bane damage to your pure offensive spells to undead and some others.
Tested this out in Neco on some undead using call lightning, produce flame, and ice storm and couldn't see bane damage with Warden II (2d6 bane damage) check using n+n+n format and with out and check combat logs.
Am I misreading this effect?
