The Warlock - a massive rewrite [3.5 Base Class WIP]

[Tacitus]

Perilous Veil is like Retributive Invisibility. If a foe sees through the illusion you have set up around your allies, they get pinged for it. The intent is for use on your allies as, now stay with me here, a Veil.

However, if you want to use one of your actions at high level to do piddly damage and some debuffs, it might work like that, maybe? A foe resisting it being cast on them isn't so much disbelieving it as negating the spell. Disbelief to me suggest that the spell is already in place and is then interacted with to be disbelieved. So the foe would have to make two saves, the first failing and the second succeeding to be struck with those debuffs and some minor damage.

Its not an inverse save, its a consolation prize.

Edit: Though I think there should be a time frame for blind/deaf/mute mentioned. If its permanent, a duration, etc. If its not permanent, then who cares?
