Everything seems good but these bits, first rule I don't really understand, it makes the squad he is in worse? and the sword is a bit weak, but still everything else seems good. but WS1 is also quite low even with BS6..this character is a vetran from the space marine wars and has learned how not to injure who he strikes his team are not as skilled
any rolls to hit by units joined by this character must be re-rolled when shooting
... [SNIP]... this sword always hits on 6+ and wounds on 5+ all wounding hits struck by this weapons incapacitate him instantly removing as a casualty they have a protection of a 6+ invulnerable while being attacked by this weapon
Thinking of including riot guns, the ones that fire large bullets but the bullets have no point on them. Riot shields would be cool to (like large stormshields).
