Prerequisite: Level 4

Effect: The companion’s frame is hardened, granting it DR 5/adamantine. At 19th level, this increases to DR 10/adamantine.

Resonance: A magical barrier protects a select few allies nearby. One ally within 30 feet gains the benefit of a stoneskin spell. The ally must remain within 30 feet to benefit from the effect. An additional ally can be targeted at 16th and 19th levels. The resonance ends after 1 minute, though it ends on an individual once it has prevented enough damage (as outlined in stoneskin).
