Tzarakk is a flexible guild, but the mounts don’t have any superb resistances to attack. This is a serious problem when fighting powerful monsters. This skill attempts to improve your mount’s resistances, but using it is not a straightforward task. If you’ve been a Tzarakk for a long time and want to kill stronger monsters, you’ll need to do some testing with this skill to get the best results.

The ingame help reads:

Although chaos mounts are extremely powerful and come in handy when in
battle, they lack some certain characteristics that more or less makes 
them equal with normal living mounts. To counter that imperfection the 
chaos priests of Tzarakk came up with this utility skill that will 
temporarily boost your steed to rise above the masses. Only after 
killing the beast, and making a mockery of its pathetic life by 
dispensing the remains in a place the beast spent its life avoiding, 
will you unveil the true power of this skill. In addition to the actual 
corpse you will also need some kind of sharp object that can be defined 
as a dagger.
(This skill works only for generic outworld monsters)
