SpreadNotDebuffed

Returns true if units inrange that are in combat do not have the debuff sent and applies the debuff.

SpreadNotDebuffed(range, debuffId, spelltocast) : boolean

spreadnotdebuffed(range, debuffid, spelltocast) : boolean
SpreadNotDebuffed(range, debuffId, spelltocast) : boolean
-- alts
spreadnotdebuffed(range, debuffid, spelltocast) : boolean

Example

if talent(6, 1) and UnitAffectingCombat('player') and
  mybuttons.SWP and health(mytank) > 95 then
  SpreadNotDebuffed(40, PurgeTheWickedDebuff, PurgeTheWicked)
end
if talent(6, 1) and UnitAffectingCombat('player') and
  mybuttons.SWP and health(mytank) > 95 then
  SpreadNotDebuffed(40, PurgeTheWickedDebuff, PurgeTheWicked)
end

Note

Careful using this. It does exactly what it implies. Literally. Think about possibly doing a check for how many have the debuff first, then if the number is lower than what you expect then call this function. If your in a party and your tank sucks, your going to be tanking. You have been warned.
