Proficiencies
Martial elementalists are proficient with simple weapons, as well as light armor and bucklers. In addition, if this is the character’s first level in any class, they may select a martial tradition of their choice.
This alters proficiencies.
Combat Training
A martial elementalist may combine combat spheres and talents to create powerful martial techniques. Martial elementalists are considered Proficient combatants and use their casting ability modifier as their practitioner modifier.
This ability replaces the elementalist’s bonus combat feats.
