Cure Skill.

[Manifus]

I was wondering, last night I got the Crusader spell 'Cure'.

I was fighting some tree's in Nifleheim and they cursed me, of course, I noticed that the description on Cure was:
"Cure Blind, Chaos and Silence (limitation: can't cure yourself from silence because you are silenced)"

I used the skill but I couldn't un-curse myself with it.
Is the skill bugged or there is something I don't know?

It doesnt say it cures curse ^_-
