I was thinking in pieces of wargear for the spacewolves

, what they could get with the update, so i was thinking in themed pieces, one of them and it doest look so crazy, a special issue wargear, a frozzen amulet, piece that give shrouded to the bearer and in the first round of combat give a -1 initiative to the enemy unit, with a cost of 25 pts. It could be conssider as relic or just a special wargear for a named character.
Another idea i have from a new weapon, taken inspiration on the psychic power, how about a blizzard cannon, a 24" S3 Ap6 assualt6 rending/-1 to the enemy initiative, maybe could be salvo 3/5 with the same effect and being a
TDA weapon only, for the wolf guard.
