how about a silence spell, to stop enemies from casting, can even work on stun/mez immune mobs. since it doesn't stop them from fighting. but will temporarily stop them them from casting certain attacks and heals. would be useful against Myloc Queen, Daknor and Faffy.
would be very similar to sorcerers ability to spellbind. can be used to stop blighted clerics from healing mobs that a healer or cleric is trying to kill.. that is so annoying
get a mob down 1/2 and a blighted cleric heals it back to full, and constantly heals after. almost impossible for some ppl to kill the mob their fighting. make it masterable like spellbind ability also. so can be used by some other classes, just as spellbind can be used.
can be spell or ability, or both. same timers as spellbind and numbing haze.
