[AB 3.1] Harlequinns?
 

Say, how do I make a harlequinns list? I can't seem to find
them...

Go into the Eldar race and into the rules selection (little clipboard) and do the following:

1. Select core/expansion lists -> expansion lists
2. Click OK
3. Go back into the rules and select Unofficial lists/addon -> Harlequins
