Torrent of Fire comes off him being able to fire his weapons twice in the shooting phase (granted by the skill Blazing Weapons in the 40k Dataslate). I think that would be pretty nasty to get in the way of.
I've dumped "Leader" as based on the dataslate, Silver-tongued is far more fitting, background and rules-wise for what he does.
The dataslate says he reduced the leadership of fellow HQ choices, so Leader is not as fitting as Silver-Tongued is.
His dataslate grants him a BS of 10 (no I don't know what that's doing there, or why it needs to be higher than 5 or 6, but there we go).
This leaves me unsure how to handle his completely abnormal BS skills. Ditto things like the hipshooting/dead eye shot. For that latter, he is known for placing shots extremely well. But perhaps I'll dump hipshooting - he still looks like he has to choose between shooting and/or sprinting for 7th edition rules.
His weapon skill, by comparison is "only" 7 on the tabletop, with a leadership of 10, and an initiative of 8.
RE:Gun-Fu, I just didn't want him to be too crazy given that he can fire weapons like a plasma pistol and bolt pistol in close combat. I mean, he's terrifying as it is, although he's hiding from actual Dark Angels, so if a GM deployed one of those on the tabletop to counter, then he'd have to keep a low profile for the entire game, or just leg it (hint hint Gav).
Note: his plasma pistol does not "Get Hot" in the dataslate either. It's an archeotech weapon, basically. Given that it lacks Gets Hot, how do I handle this?
But yes, I do think he might - if needed - use the pistol butts as close combat weapons.
New problem - Dataslate says the sword gives him "Eternal Warrior" (Immune to instant death), and Shrouded (bonus to cover saves).
Shrouded I'm not sure - represent with Stealthy maybe?
Eternal Warrior just boggles the mind given that marines are - as stated - already a nasty proposition in any Inquisitor game.
I mean, he's already got Dodge and Heroic, so maybe that counts enough? I really don't know.
