No easy way.
You can only check for specific abilities if the hero got them, but doing this for all abilities would use quite some performance.
You better create an ability array consisting of all abilities the hero could possibly have an iterate through it to decrease the number of checks needed.
Sadly its probably easier to do alot of comparisons using an Array storing the abilities as said above. That may take awhile though, also you will need to type the message code for each ability as there is no way to take the Name of the abilities and change it to String form as far as I know of. (The Raw Code maybe, not sure)
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
