Martyr's Sacrifice
Starting at 1st level, this ability has the following effect:
Whenever the dauntless defender's partner takes three (or more) points of hitpoint damage, a portion of that damage is redirected to the dauntless defender, in which case the dauntless defender loses a number of hitpoints equal to 33% (rounded up) of that damage (instead of 0%) and his partner loses a number of hitpoints equal to 66% (rounded down) of that damage (instead of 100%).
Note: If the dauntless defender is immune to the type of damage that was dealt to his partner, this effect will not activate.
When the dauntless defender reaches 3rd level, this ability gains an additional effect:
While they remain linked, both the dauntless defender and his partner gain healing amplification 33%.
When the dauntless defender reaches 7th level, this ability gains an additional effect:
While the dauntless defender's partner is subject to a detrimental effect, the dauntless defender can spend a free action in order to transfer that effect from his partner to himself; for the remaining duration of that effect, the dauntless defender's partner remains unaffected by it, and the dauntless defender suffers any penalties/restrictions/etc. that that effect would have otherwise inflicted upon his partner.
Note: The dauntless defender cannot transfer an effect from his partner to himself if he is immune to that type of effect.
