Hunting down information and targets has been what you have been trained for most of your life. Using your dark powers to utilize the shadows as your tools you have turned them into a reliable companion. Now as you grow in strength, so to does the power you lend to the shadows in order to accomplish your tasks. 

When you use your Hound of Ill-Omen ability, it summons the Sarvara Wolf to your side instead, a creature born from the depths of chaos and darkness and bound to do your bidding. You may only have one Sarvara Wolf active at a time though you may still use your Hound of Ill Omen to summon more wolves normally.
