The trait is another reason I left a named keyword off of Walter, he's already going to be giving the Monster keyword a hefty boost defensively speaking (at least for range/line of fire), and possible offensive buffs. He's basically giving Monsters a pseudo-team ability as is without having to benefit from named keywords.

While I'm posting, I shortened a few ranges in the set after looking back. Range: 4 for the skeletons is now Range: 3, and Trevor now only has a Giant Reach of 2, instead of 3.
