@Seducer:
As long as the eidolon has 1 or more hit points, the summoner
is protected from harm. Damage in excess of that which would
reduce the summoner to fewer than 0 hit points is instead
transferred to the eidolon. This damage is transferred 1 point
at a time, meaning that as soon as the eidolon is reduced to a
number of negative hit points equal to its Constitution score,
all excess damage remains with the summoner.
