Love the optional purchase methods to prevent forever bad rng, hopefully they implement other methods like this in the future.
Bonehoof Tauralus does drop, I have only seen it drop for necrolords though.
They could at least make it 100% clear in the mount log that it's only lootable by a certain covenant. Would save a lot of wasted time for folks.
" (however, there is currently a glitch that allows this rare to be killed with pet and AOE attacks);" isn't this fixed?
