Will of the Dynasty
Effect: This Merit reflects the degree to which identities
begin to merge when Kindred become part of a cyclical
dynasty. Telling (or forcing) the Kindred to do anything
that would harm or betray a member of his House is
tantamount to asking him to perform that same action
against himself. Telling him to kill a member of his House
is equivalent to telling him to commit suicide, for example.
All rolls to compel the Kindred to take an action
that threatens or endangers his House allies (through
Skills, Disciplines, magic or any other means) are automatically
modified as though the character had spent a
Willpower point. That is, either the character’s dice pool
to resist such compulsions gets a +3 bonus or the
character’s Resistance Trait is temporarily increased by 2.
Likewise, the character gains these bonuses when a member
of his House attempts to betray, mislead or lie to him.
