The Powerhouse feature for the Juggernaut Brawler subclass doesn’t mention that one can spend 1 Stress to target two creatures with the same melee attack when viewed on the character sheet (though it is shown on both the class overview and the Foundation card shown in the character builder). Likewise, the Subclass specialization feature Rugged doesn’t mention that this part of Powerhouse is increased to three three creatures.
If this is from the most recent playtest document 1.5 that was released we’ve not had a chance to update to that just yet. It’s coming but I don’t have an exact timeline at the moment. If it’s not from the 1.5 playtest material please let me know and I’ll see what we can do!
