Masterpiece Activation Time

[DrakeRoberts]

Some masterpieces can be found here:

What is the timing on masterpiece activations such as that of The Dumbshow of Gorrac, which is "1 full round", versus that of The Lullaby of Ember the Ancient, which is "1 round"?

That is to say, what actions does it use up on my turn, when does it take effect, etc.? Thanks!

I believe they are one and the same, taking affect at the start of your next turn. At least that's how it would translate with regard to spell casting.

I always thought it was the difference between "1 full round action" and "1 round action". The first one starts at the end of your turn (after you spend your full round action), the second only takes place at the start of your next turn. That's for spells but I can only assume that the masterpieces were meant to be the same.

A full round action takes your full turn, and comes into effect at the end of said turn (when you've completed the action).

1 Full Round takes a Full Round Action as well, but doesn't take place until the start of your next turn.

So then full round and one round are the same, since these are full round and not 'full round action'?
