Unification Source
"This Ritual allows the bearer of the Target Source to expend 100 points from their Channeling pool to grant themselves a Ritual Strength of 1, exclusively for the purposes of acting as a secondary Ritual caster, in Ritual castings of the Aspect appropriate to the Channeling points expended."

¿Can the user of US expend additional Channeling to increase their Ritual Strength above 1?
¿Can the user of US increase their Ritual Strength through other means (e.g. Ritual Reinforcement)?
The ability grants them a Ritual Strength of 1. It does not increase their RS by 1. Additional purchases beyond the first would not have any additional impact.
The prereq for Ritual Reinforcement is a 9th level spell slot of the appropriate aspect, which, because they need HM to be able to purchase HM abilities, means they would already have an RS of 1 or more, which would make the use of Unification Source redundant.
