Im assuming you're talking about a condition and you're coding in GUI, if so so then yes there is:
(Level of Your Ability for (Attacking unit)) Greater than (>) 0
Add an Integer comparison then select "Unit - Level of Ability for Unit" then just set what ability your checking for.
What the condition does is just check if the level of a specific ability for the attacking unit is greater than 0 obviously if it is the unit must have that ability.
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
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.
