Enchant stacking

im an i monk and i regularly duo farm UW. however, i was wondering what the "stacking" is on blessed aura and an axe with an enchnating mod? do they stack at all?

Yes, they do stack. The bonus is given as a percentage of a percentage. For example:

You have a basic skill that lasts 10 seconds, but also have blessed aura (20%) and an enchant mod on your weapon (20%). The skill gets boosted up to 12 seconds counting the blessed aura, and then boosted up to 14.4 seconds after factoring in the enchant mod.

ok thanks for the quick reply, another question, are there any skills like blessed aura for other proffessions?
