Benediction of Sanctity RK 2 and 3 are not being added to my blocked spells. I right click each time i see it and add to blocked list but it keeps showing up in my buffs.
Could you have hit the limit on blocked spells? Don't recall what it is but I think there is a hard limit on how many can be added.
My guess is you've hit the limit. Try removing some lower level spells from the blocked list and see how that goes.
