One of Radovan's powers, if you choose his demon form Fell Viridio, says "on your combat checks that do not have the 2-handed trait, add 2 and the poison trait". Does this mean that if you choose Fell Viridio for the encounter, that you automatically lose to all undead? It doesn't sound like the poison trait is optional, so if you roll a combat check against any undead monster (they're immune to the poison trait), you can't kill it. Is there something I'm missing here? Is the effect optional, or is Fell just a bad demon form?
