Sometimes treasures are named aptly ie.
ypBuildingHP
ypBuildingSpeed
ypPopulationBonus
afBuildingSpeed2
etc.

Others are more obsure.

afKola: gather rate for trees
afKola11: gather rate for trees
afShaka: 50% more damage to Hero
afYodit: siege damage to infantry.

Bone guard treasures can only be picked up by SP Black family heroes.
i.e.
BoneguardAmor
BoneguardWeapons
