Spirit Walk

Spirit Walk stealths the spirit beast. Movement is reduced to 50% of normal. First attack out of Stealth does 120% of normal damage. Can be used with Dash (pet).

History
Originally Spirit Beasts had the Prowl (pet) ability, however it was brought up by a few players that some Spirit Beasts such as Arcturis would seem very unrealistic 'prowling' and threw into question future Spirit Beasts that could take the form of flying creatures. Thus it was suggested to change the ability to Spirit Walk. As such, Spirit Walk is identical to Prowl in all but name.

Trivia
An ability of identical name exists in Blizzard Entertainment's Diablo series.
