Talk:"Zeta Leader"/@comment-12.10.219.225-20151218175619/@comment-82.234.82.165-20151220131908

The FAQ expressly states that Yorr's ability negatively interact with abilities and upgrades that specify receiving a stress token is a "cost" part of the ability, as it is with Zeta Leader's ability: "... receive 1 stress token to roll 1 additional attack dice." (emphasis mine)

It is even specified that if you actually tried to do that, Yorr would get the stress and nothing would happen. Luckily, Yorr's ability is optional ;)
