Diablo – How does “Increases bonus experience” on items work

diablo-3

Leoric's Signet, Cain's Fate (set bonus) both give bonuses to experience worded like this:

Increases Bonus Experience by X%

I don't have either of these to test it out, but I'm curious to see if they are worth the investment.

Do these items work like a Ruby in your helm socket, increasing the experience for monster kills by 30%?

Or is the affix read literally to mean it increases only your bonus experience? I.e., with a 30% ring and you have +100 xp per kill, the effect increases that to +130 xp per kill.

If the latter, what qualifies as bonus experience? Just +XP per kill? What about NV stacks? What about a ruby in your helm?

Both seem like legal interpretations of the wording, but it is a huge difference in the attractiveness of the items.

Can anyone shed some light on exactly how Leoric's Signet and the Cain's Fate set bonus work?

Best Answer

It works exactly the same as a helm ruby. Both items increase the "Bonus Experience %" stat on the character sheet. Despite the somewhat confusing name, this is a % increase to the base experience gained for each kill.
