Twilight/Celestial Wings Mechanic

[Fellhound]

So I'm looking at the tier 5 ToH wings and I come across the Dark Allegiance Twilight Wings.

The item description says it adds a 2% chance to cast a myriad of skills.


So what happens when this effect triggers?

Will all the skills be cast or is the chance separate for each skill?

Or perhaps the skill that gets cast is dependent on the wearer's class?

I ask this because I'm not sure how level 2 Bash would work with a bow or a gun...

Also, how would the Anolian card work if added to this wing?

An 8% chance to cast Attention Concentrate? (2% + 2 * 3%)?


Could someone with either one of these wings fill me in on how this works?

Thanks.
