Shocking Harpoon

Your ship's harpoon has been modified, allowing it to conduct bursts of energy into the harpooned ship. A harpooned ship has disadvantage on the contested Strength (Boost) check to remove the harpoon. Additionally, as an action on each of their turns, a crewmember can deal lightning damage to a harpooned ship. The damage is equal to one of your ship's Shield Dice + your ship's Strength modifier. Finally, when your ship makes a Strength (Ram) check, it can reroll one of the dice.
