I know each of the medallions boost their traits by 2, but how do we find out which traits get boosted by each medallion?

Im guessing Dressage boosts Mvt, and Int, but not sure what else.

Cross Country I'm guessing boots speed and strength but what else?

m just really confused how they work so don't know which I need. Any help greatly appreciated.

Dressage = Mv Int Str

XC = Hrt Spd Str

Jumping = Hrt Scp Spd

This info is available in the game guide under Your Horse.

Thank you
