Necrotic Eruption
Necromancy [Evil]
Level: Clr 6, sor/wiz 6
Components: V, S, F
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Target: Living creature with necrotic cyst and all creatures in 20 ft. Radius spread
Duration: Instantaneous
Saving Throw: Fortitude partial
Spell Resistance: No

You cause the cyst of a subject already harboring a necrotic cyst
(see spell of the same name) to explosively enlarge itself at the
expense of the subject's body tissue, harming both the subject
(and nearby creatures if the subject fails his save). if the
subject succeeds on his saving throw, he takes 1d6 points of damage
 per level (maximum 15d6), and half the damage is considered vile
damage (see necrotic bloat). The subject's cyst-derived saving throw
 penalty against effects from the school of necromancy applies.

If the subject fails his saving throw, the cyst expands beyond control,
 killing the subject. All creatures within 20 feet of the subject take
1d6 points of damage per level (maximum 15d6; Reflex half), and half the
 damage taken is considered vile damage. All creatures in range that take
this secondary damage are also exposed to the effect of the base necrotic
cyst spell. On the round following the subject's death, the cyst exits the
 flesh of the slain subject as a free-willed undead called a skulking cyst.
