A fetch with this Echo is dangerous not because of what it can do to the changeling, but because of what the changeling can do to himself. The fetch spends one point of Willpower and one point of Glamour to activate the power. For the rest of the scene, any damage inflicted upon the fetch from any source is also visited upon the character. The fetch and the changeling have to be within line of sight of each other when the power is activated, but they may separate thereafter without dissolving the bond. Regardless of the type of damage inflicted on the fetch, it heals from the changeling like bashing damage. The damage is still counted normally for purposes of killing the changeling, though. That is, if a fetch with Health 7 suffers seven levels of lethal damage, both characters start to bleed to death. If the changeling is saved, though, the damage heals at one point per 15 minutes.
