Divinity runes any good?
divinity is bad, it’s literally less DPS than ruby orbs.
prepatch if you aren’t using scholar the 2nd best DPS is ranger because the 6 bonus is bugged and always is up; post-patch strength runes will also be a good choice (maybe others too)
Nope, unfortunately they’re horrible. Anything that you’d actually gain from it is so negligible that there is absolutely no way it could come close to offsetting how much you reduce your own potential by using them in the first place.
