I have (awesome) Grand Melee Robert on the table, I have three troublesome opponents sitting opposite me, all with juicy looking power tokens on their house cards.
I represent with Robert in a power challenge against Opponent 1 (Hernando), alone. Hernando declares some puny little defender, Opponent 2 (Wolfgang) sends a little girlyman to Hernando's assistance, Opponent 3 (Cornelius) does nothing.
Robert beats both of the defenders combined, he doesn't even break a sweat.
What happens next? Obviously Hernando owes me a power token, but do Wolfgang and Cornelius?
My reading of Big Rob says that, regardless of who does or doesn't defend, if he attacks alone in a power challenge then all opponents owe me power when he wins (regardless of whether some, all, or none of them declare defenders). Is that right?
