Life drain buffs

I'm trying to make a channeling spell based off of life drain. The problem is, theres like 8 buffs on the ability and I dont want to show the graphics of life drain. "Drain Life (Target), Drain Mana (Target), Drain Life and Mana (Target), Drain Life (Caster), etc..". I tried deleting all the buffs, and just adding target and caster "Drain Life", removing the graphics but it didn't work for the target (it did remove the effect for the caster). I also noticed theres 2 buffs not found in the Buff Editor which you cannot alter, simply labled (Drain Life, Siphon Mana). So.. how do I go about doing this correctly. I just want the channel effect, without the graphics on the target unit, and I don't want to use the channel ability.

Why not just use custom life-drain buffs (all of them) with with the art removed, hmmmm?

I eventually got it the way I wanted it. Instead of creating custom buffs I just deleted the art off of all the buffs available for edit.. I didn't want to do it this way in case I used the real life drain down the road, but I dont feel like messing with much because I'm lazy.

Copy and paste is hard?
