Necrotic Phlegm (new spell, MU 3)
This spell allows caster to spit highly corrosive, toxic mucus. Range of spit is about 3 meters, any non-magical armor provides only partial protection (-2 to AC). Victim recieves 1-8 damage and must pass save vs. Poison to avoid rapid septic infection (after one round -3 to-hit and -1 to damage due to severe pain and convulsions).
Caster of the spell may spit phlegm once for each of his experience level but can do it only once per two rounds of combat. In addition, this spell leaves him / her with horrible aftertaste.
