Hi all,
I got a question that came up when I talked to another GM from our group. For the background, we started playing Deathwatch with exchanging GM's and recently one came up with the Arc of Lost Souls campaign(for those who haven't played it yet - little spoiler alert!). Due to the alternation we talk a lot about the game mechanics and how we adjust them in some cases, to prevent rule abusing.
So back to the case, when it came to the fight with the beast of thule, it ended rather unspectacular, once our assault marine could land a hit with the thunder hammer, knocking the beast to the ground, going prone. From then on things were pretty easy(target on the ground and cant dodge/parry anymore), leading to fate-burning on the beast side(and a funny expression on the face of the current GM).
So in hindsight I talked to another GM of the group about how to counter the concussive effects from the thunder hammer, to prevent excessive hammering in the future, but so far we couldn't come up with good ideas(except throwing tanks at the players), so I thought maybe I'd just leave the question for a bigger group, so please tell me your opinions/ideas.
