Transcend Mortality

You feel your body surge with mystic power that rivals that of the gods themselves.

Transcend mortality was created as a last-ditch effort, a spell to use when all other options have failed. For the duration of the spell, you are all but indestructible. You gain the following benefits:

• Damage reduction 30/epic.
• Spell resistance equal to 21 + your caster level.
• Acid, cold, electricity, fire, and sonic resistance 50.
• Immunity to ability damage, disease, energy drain, poison, and death effects.
• +10 enhancement bonus on all saving throws.
• You do not need to eat, drink, or breathe.

Although this spell makes you effectively unkillable for the duration, that comes at a horrific price. You gain these benefits by using up all your remaining life force. When the spell ends, you are instantly slain and reduced to a pile of dust (as disintegrate). This effect allows no save and can’t be prevented by any means, though you can be resurrected normally afterward.
