Getting ready for the new raid, I thought I'd craft a dragon-beater for my warforged artificer. Usng a 2[w] repeating heavy crossbow for the base and Greater Dragon Bane for the suffix(obviously), but what is a good prefix for such a weapon?

I know a lot of dragons have elemental resistances, so elemental burst is probably unwise. What about Holy? Vicious does not work on ranged weapons.
