The weapon relics replace an existing weapon, so in order to not lose the force weapon, you need to buy a standard storm bolter for this guy first. This poses a problem as you have no spare points.
Just one I'd say - now that Rad is worthless, you're only really wanting the
GL for the Stasis shell, don't lose any more firepower.
An Auspex on the biker Libby would fit well too. Again, no spare points.
If I had to drop something, it would probably be the Assault Cannon from the Darkshroud, as it needs to Jink for any kind of survivability.
