Quick Deadeye Earring question

[Antithesis]

Searched through the Wiki's and KI didnt find anything as to how long it lasts. Anyone know how long it lasts? Pardon for the silly question.

about 3mins? I think. I've never timed it, but usually it was still on by the time the mob was dead, referring to dl/kv. I'll burn a charge on my next earring to find out.

Probably 3 minutes, pretty sure the MAB enchantment ENM60 item is 3 minutes as well.
