Yes, but I want the combat experience to provide bonus only for units that have "Specified behavior".
I.E. My map has neutral minions, some of them are the same as other spawning minions. I am aware of the above fields but modifying those will change XP bonus for killing all units, not specific units with behaviors.
My neutral minions have a behavior that marks them as "neutral". And also marks them as different from other units of the same type that may be roaming around the map.
Furthermore, the hero needs to have "normal" experience when killing the nuetrals, and then have the % bonus buff ONLY against the "nuetral" minions after he has purchased his special item / buff. You can't simply just modify XP Bonus and get a bonus against only nuetrals.
