Energy Shielding (Ex)

Effect: The companion is shielded from harmful energies. The vanguard must choose from acid, cold, electricity, or fire. The companion gains resistance 5 against that energy type. This resistance increases by 5 at 5th level and every five vanguard levels thereafter. This augmentation can be chosen more than once. Each time it is gained, it must be applied to a different energy type.

Resonance: The companion dampens energy effects nearby. Effects within 30 feet of the companion that deal damage of the chosen type have their damage reduced by half (50%), rounded down. This resonance lasts for 1 minute.
