detecting necrotic cysts and necrotic tumors

[sleepyphoenixx]

Detect Magic will detect the active spells, as well as identify them as Necromancy school.

Spellcraft will allow somebody witnessing a victim operate under the effect of Necrotic Tumor identify the spell in place.

Necrotic Cysts are instantaneous, so those two won't work. They can detect the Necrotic Tumor spells on the leaders though if they're viewed with Detect Magic active (or some other way to see magic), which should prompt the clerics to look closely for Necrotic Cysts and other asssorted shenanigans.
Necrotic Tumor can be dispelled normally, but Necrotic Cysts require a DC 20 heal check to remove.
