Chorn said:He obviously loses the spell slot used to cast the spell so it's probably safe to assume items used and spells cast would not be restored but what about damage and active effects? If the caster was hit for 10 points of damage and cast mage armor on himself in the minutes before rewinding himself, would he still retain his injuries and mage armor or would they cease to exist on account of not having occured?
Finally, since it only rewinds the caster while still keeping him in the same timeframe, what possible use would someone have for this spell that would not be achieved by simply teleporting away? Teleporting avoids the memory loss and allows you to precise control over your destination for the Times when hopping back somewhere between 2-7 minutes ago might be a bad idea.
The caster would still have those ten points of damage, and X minutes of duration would be used off of his Mage Armor.
Eh, as I've stated, it's really just an NPC spell. Still, if a PC wants to take it, that's fine. It isn't meant to be a very good choice for a PC though, thus I should never have to adjudicate it. But, you never know.
