Part of the description of Boon Focus II is:
If the invocation time for a boon is 1 minor action, it can be invoked only once as a minor action.
My confusion comes from the last sentence. It seems the last sentence imply that each boon invoked as minor action is considered separate, and you can invoke two or more boons as minor action.
For example, with Boon Focus II: Bolster and Boon Focus II: Barrier, I can invoke both boons at the same turn as minor action. I don't need to sustain both boons (first turn it is invoked is free) because (or as long as) I don't sustain any other boon.
I was expecting the opposite - you can only invoke one boon as minor action, because you can only take one kind of each minor action, in this case: Invoke Boon. The only way to get around this rule is to consider each separate invocation as different kind of minor action: Invoke Boon Barrier, Invoke Boon Bolster.
Can I invoke multiple boons in one turn using minor actions if I have two different Boon Focus II?
