You have the Elemental Strike feat. ELEMENTAL STRIKE (Source: Homebrew by LeonidasTDD) You have learned to harness elemental energy and channel it into your weapon attacks. Choose one of the following damage types; acid, cold, fire, lightning, or thunder. When you hit with a weapon attack (melee or ranged), you can choose to channel that element into the strike, dealing an additional 1d6 damage of the chosen type. This additional damage increases to 2d6 at 6th level, 3d6 at 11th level, and 4d6 at 16th level. You can’t use this feature again until you finish a short rest.
