XP gained from stuff

[Blamelance]

Is there any way to make hero gain a certain amount of exp from killing a unit without having to make a certain scrift for every unit killed?

and is it possible that there a way to apply the "Tier bonus factors" to Units and Buildings or is that for something else?

You mean enabling bounty on units?

You can always do:
unit dies
type of dying unit = footman
add 50xp to killing unit

I know, that's what I mean by "scrifts". Can I connect units to gameplay constants to bind the tier so some units reward the same amount of xp?

There seems to be some kind of exp base too since I have a gold bounty and they get exp too. What's the connection?

You don't need to. Just check unit type of dying unit.

Or you could start by setting the custom value of all units of a type to number of XP you want.
Then just make a trigger that adds custom value to XP.
