Not to diss you or anything, but have you ever played an invoker, or for that matter, transmuter?

>"Time Heals All Wounds"

Also known as slow/metabolic slowing. Invokers will never have slow as a spell, that I'm fairly sure of.

>"Blast of Aging"
>This blast causes the victim’s body to age considerably.
>Though it is only temporary, the shock disrupts the body,
>causing damage.

AKA haste on crack. I think this would be more in line for a transmuter or temporal mage (good old blue mage).

>"Time Capsule"
>Caster cannot move or perform any action (including talking)
>except step out of the capsule. While under it’s influence the
>caster does not regenerate, but cannot be harmed in any way.
>Can be dispelled as normal. (Considerable lag for caster)

I'd file this under overpowered.
