I was looking through the Comprehensive Rules Document and saw this:
Interference with mandatory costs From the point when the action is announced legally to the point where the individual cost is required, if payment of any of an action’s mandatory costs is interfered with, the player taking the action may choose to pay the costs another way, or choose not to pay the cost.
Based on this, another question came to mind. Are you always allowed to let an action fail by not paying the cost (i.e. I play Kami Unleashed but then decide not to bow my personality to pay the cost and allow the action to fail)? This seems relevant for 2 reasons. First, would it count as an action for any rings (Air, Void, and Water specifically -- since they no longer need to be successful). My main concern is with Reinforce the Gates. If I announce Yoritomo Sunagawa's battle action and my opponent plays Reinforce the Gates, can I choose not to bow a follower and allow the action to fail (since it will fail anyway).
Thank you!
