Whisper's Dicey Healing Gate
(Necromancy)

Range:  20 yards
Components:  V, S
Duration:  Special
Casting Time:  4
Area of Effect:  One creature
Saving Throw:  Special

This powerful spell opens a small gate to the positive material plane inside the target creature. If the creature wishes, he could attempt to resist the spell by successfully making a saving throw versus spell, in which case the opening of the gate fails. The caster must upon casting the spell decide for how long the gate should remain open. The caster can attempt to maintain the gate for up to 1 round per three caster levels. However, such a gate is not completely stable, and the actual effect will be 1 to 2 rounds longer or shorter (roll 1d4: 1 = 2 rounds less, 2 = 1 round less, 3 = 1 round longer, 4 = 2 rounds longer). The effect of such a concentrated gate inside the target's body is the following. The positive radiance will add 2d10 HP to the creature per round of exposure. However, if the total amount of hit points is exceeded (the creature is fully healed, but the gate remains in effect), the hit points will temporarily be added, but with the cumulative chance of 20% per round of "overloading" that the creature's body receives a surge of radiance, causing the body to explode. If the body explodes in this manner, there is no way to bring the creature back to life.
If hit points are gained beyond maximum, without exploding, those hit points will remain for 20 rounds and then recede by one point per round until regular maximum hit points are reached. An exploding body will not hurt bystanders, other than bowling them over, and thus maybe causing 1d6 HP falling damage or something like that, but it will definitely smear the area around the exploded creature with the creature's blood and itty bitty pieces. This spell should only be used in dire emergencies, or can be used as an attack spell on an as yet unharmed creature.
Only living creatures are affected by the healing process. If the spell is utilized on undead, the effects will be spectacular. The undead will be allowed a saving throw, but if the saving throw fails, it will explode in a brilliant explosion, shattering the physical body, if any is possessed, into tiny shards, and causing the psyche to be utterly annihilated.
