Noble Steed

Cantrip (This spell consumes no mana, but can
only be cast if you have at least 1 mana available
of the corresponding color. Only 1 spell with
Cantrip can be active at a time).
You get +2 on you rolls when trying to tame and
mount a Creature. You get +3 if that Creature is
a Horse.

Treat him well, and he will do the same to you
