Sturdy dragon and Sturdy Raven suck
I am a lvl 36. My current Paladin cohort is 58. The kingdom won last kvk and I got sturdy Dragon and Raven. +700 attack or defense. Sounds cool. So I tried them out today. Both of them. On Paladin cohort 59 and after I increased some shaman weaponry and of course my VIP level thanks to the gold event and the birthday promo. So guess how many cohorts I managed to destroy... I bet you wouldn't expect ZERO for an answer, would you? Yes, I wore the right gear and used the powerboosts, and my aes was activated. Everything was in place. And I couldn't beat an single cohort more. Isn't that completely useless? I tried both with the same result. I don't feel I wasted them because they did nothing anyway. They simply are crap. If that is to be the big extra reward for Fury, don't bother.
