I just thought of an idea for a PVP spell, going with the nethershifting everyone's been talking about for pets.
Nethershift: Shifts the Warlock into a lesser invisibility state where they can see hostile enemies, however attacking cancels effect. Lasts 10 seconds unless canceled, during duration you gain 10% regeneration to health and mana, 2 sec cast in which if attacked is canceled. 2 min CD
Tell me what you think, if over powered, tell me why and try and to make it not over powered. If stupid, well, just say so in a polite way, its christmas anyway.
Take care and Merry Christmas!
