Stunning Howl (Su): Once per minute, a tyrg can emit a supernaturally loud howl. This mournful howl can be heard for miles, and any creature within 30 feet of the tyrg when it howls must make a Fortitude save (DC 18) or be stunned for 1d4 rounds. The tyrg itself is immune to the effects of its own howl, but other tyrgs are not. This is the primary reason the creatures are not pack hunters.
Skills: The tyrg gains a +4 racial bonus on Listen and Spot checks, and a +8 racial bonus on Hide checks.
A tyrg begins combat by unleashing its stunning howl before rushing in to savage the stunned prey with its jaws.
