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 are more accostumed to fire and therefore
more resistant to heat. You get -2 Damage from
all Fire attacks and sources.

Did you know that one of the ancient ways to light
a fire, was to use one ember from the last fire? That
way, all fires were one fire...
