Move 30% faster (The Enchant Boot - Minor Speed enchant has no effect on Ghost Wolf speed)
Attack with a bite attack (damage and attack speed depend on what weapon the shaman has equipped) even if you have 1 weapon skill in wolf form you will have full skill.
Become hard to see by other players (though this won't affect aggressive mobs).
Your ability to loot, skin, and gather herbs remains usable.
If [Rockbiter Weapon] has been cast prior to becoming a wolf and the shaman keeps that weapon equipped, it will significantly increase the damage done with each bite.
Passive abilities from Weapons and Items and procs are not active.
Certain buffs from potions and some spells disappear.
