c 'power word curse' war-weary
You point to a war-weary storm giant and say 'Taint'.
You feel unclean.

Checked right after and the spell target isn't cursed:

c curse war-weary
You proclaim a curse upon a war-weary storm giant, but his soul remains untouched.

Also not sure if it's meant to stack like this:

Though I added echoes to the room when someone gets cursed.

After hundreds of casts (the spell's at 94% now), I have never been able to do anything besides cursing myself (unless there are no messages). It also seems too easy to cancellation/uncurse.

Thought the new messages had taken effect. I'll try it again in a few days.

I tried the spell again on some slept lowbie mobs (young cloud giant, Happy Farmer, a farmer). Out of the 40 times I cast it, I cursed myself 4 times, and got no other messages.

I think the problem is the spell simply does not land on targets. I tried to dispel the mobs after 10+ casts of pwc on each, they were not cursed. Normal curse worked on them still, with no message about them already being cursed.
