Elemental Burnout

Starting at 7th level, an elemental engine gains additional benefits while at maximum burn, depending on the element she chose at 1st level. If the chosen element was air, you gain a +2 bonus on saving throws against spells with electricity descriptor. Additionally, you gain immunity to ground-based spells and abilities. If the chosen element was earth, you gain a +2 bonus on saving throws against spells with acid descriptor. Additionally, you gain a +4 bonus to CMD against trip, bull rush, and pull combat maneuvers. If the chosen element was fire, you gain a +2 bonus on saving throws against spells with fire descriptor. Additionally, you gain a +20 enhancement bonus to your speed. If the chosen element was water, you gain a +2 bonus on saving throws against spells with cold descriptor. Additionally, any enemy striking you in melee combat with a non-reach melee weapon must make a Fortitude saving throw (DC 10 + half the kineticist level + Constitution modifier) or become slowed, as per the slow spell, for 1 round.
