Thur, is there something for the "if...then" option for when a skill "unlocks"? I know there is If Skill is Usable thing but that doesn't quite seem to be what I want.

Yellow RKs have a skill called Static Surge that only becomes usable after using another Lightning based skill is used and some randomness "unlocks" static surge. Otherwise it's just always greyed out.

Static Surge is one of those skills that will show up on the default auto skill bar when it's available to use. I normally hide the auto skill bar in my UI Skin because it's annoying for most classes.

Basically, I'd like to make an icon for Static Surge appear on the screen to let a person know it's available to use without having to look at the hotkey itself at the bottom of the screen.
