Prodigy of the red bloodline

Any fire your character produces is so hot it has turned blue.

Whenever you fail a hit roll (signifying a miss) whilst the attack contains a fire damage component. The target takes one roll of that fire damage's dice anyway as "heat" damage

For example a missed Scorching ray beam will still deal 1d6 fire damage, but a chromatic orb deals 1d8 fire damage.
