Here's a chunk of the example of play:
The goblins on the fumes, though, they're coming right at Rath."
Ben jumps in. "I step between Rath and the crazed goblins and make myself a big target, drawing the goblin's attention with a yell."
"Sounds like Defend" I say.
"Okay, I rolled a 7, so I hold 1."
"Great. The three goblins on fumes pratically bowl Rath over as they slam into him, swinging their daggers wildly."
"No they don't!" Ben says. "I spend my hold to get into the way and direct the attack to me."
"So Brianne steps in at the last moment, pushes Rath out of the way, and the goblins lay into her instead. Looks like 5 damage.
It sounds to me like in this case, the attack of 3 goblins is treated as a single attack in terms of the hold required for defense and (probably) damage as well (it doesn't say what die or dice is rolled to yield the 5 damage).
So, really? 1 hold can redirect any number of attackers? And multiple attackers just do the same base damage? 'cause that seems to invite players to undertake the not-terribly-plausible strategy of "try to get them all to attack me--it won't do any more damage than one of them, and then they can't attack anybody else."
What am I missing?
