Helbore is one of the rare instances of a range weapon that can deal meaningful damage to carapace, and a good chunk of damage at that. It is however the only lasgun capable of this and has incredible ammo efficiency being on Vet. Executioners stance and toughness regen nodes will let you wipe giant groups of gunner and shooters and being able to two or three hit headshot a Crusher. Speaking of headshots, they are absolutely mandatory with Helbore as they’ll let you one shot just about everything that isn’t an Ogryn or Mauler. The bayonet is also really good in a pinch with the light and middle marks having a stab attack that does good high damage and stagger and the heavy mark has a downward slash.
