If the spells and special abilities a mob has were listed it would be a great help for preparing against them.
A simple list with the spells they cast, special abilities they can use, and any buffs always on them would be extremely valuable information to have access to. It wouldn't have to be the exact spell either. Simply "Damage Shield" or "Direct Damage (max. damage)" would be enough in many cases.
I hope you can add this. It would be great if you could. :)
