El problema de este spell es que sigue dando el alto aggro en otras presencias... cuando no deberia.

WotLK Patch 3.3.3 (2010-03-23): This ability now causes a very high amount of threat while the death knight is in Frost Presence.

y lo que dice el spell:

Chills the target for X Frost damage and infects them with Frost Fever, a disease that deals periodic damage and reduces melee and ranged attack speed by 14% for 15 sec. Very high threat when in Frost Presence.
