I suppose it's a glitch, because Wiki says the opposite, but apparently can get 50% cowardce from one roar of Yuti. Well, Ark, you are glitched for good! Otherwise how could you explain that my friendly meeting with Yuti on Extinction ended up almost scaring the new baby Reaper out of my own?
P.s: never got it again for some reason. Another reason to believe that it was a glitch.
Since i cant find this anywhere. Reapers take reduced damage naturally so its a good soaker. Dont bring light pets near theese because they take more damage and deal less damage.The reaper burns when light is near it. Nameless will attack it tho. Sorry for bad english.
