Removing Buffs

If I remove a buff from a unit using call UnitRemoveAbility(unit, Buff_ID), will it also remove the effect attached to it? (Like, say, chill)

If not, what is the best way to go about removing a single effect of a buff? (Instead of all of them).

I'm considering using Anitarf's ABuff system, but only if I have to, or need to do this an excessive number of times in a large number of situations.

ofc. it's the sense of removing it.
yes the best solution is to use custom buffs.
