Necro aa description bug

Necro -- focus tab -- Defiler's Synergy

Am currently at rank 10 of 11 and the amount of increase to DD and DoT does not display a number for either rank. Instead it says it increases them by #X% for both ranks.
(am unable to check previous ranks since I have them already)


Also, not really a bug but a vague description for for Gift of the Grave AA under the Class tab.

This passive ability allows your weapon configuration to trigger a buff. ???????
