Hey Uberxael. In my current game, my lizardmen gain bonus strength when they are able to brace their tail back on the ground. So it's a balance out Move, limiting actions but boosting what can be done with strength. Hope that's of use. Cheers.
It would really help if you posted more often in Rogue Trader. You're the only one on the ground besides Kaius right now, so if things go bad for him, you're the only one who'll be able to help directly.
