Sometimes buff checks don't work (Crimson Scourge for Blood DKs and Dream of Cenarious for Druids). Here is a workaround that fixes that..

 

Instead of using a buff condition, use LUA script.

name, rank, icon, count, debuffType, duration, expirationTime, unitCaster, isStealable, shouldConsolidate, spellId= UnitAura("player", "BUFF_NAME");retV = count;

Return value var needs to be retV and return value research needs to be 1.

 

Simple as that.

discupe my question, but could you give me an example of how serious a skill ?

That is, a "Alternate to buff" Functional
