Today I made a small attempt to kill revenants, just to test their strength.
I first met a lv 126, who I got to just below half health, he then disappeared, I think because he had strayed too far from his patrol, or something?
Afterwards I met 2 lv 75 Rev Werewolves, got 37gp from one, and 115gp from the other...
I saw another lv 126, possible the same one, and discovered they are EXTREMELY strong! He was hitting 30+ on me, and healing much faster than I could hit, even with a drag scimmy.
Even the lv 75s put up a good fight, so god knows how anyone kills a rev dragon!
