Very Rare

An Arcannon is a cannon with no loading or firing openings. Instead, it has a powerful magical conduit running through its core that branches into four crystals on the loading end. Four spell-casters can use their turn to take the magic action and expend spell slots into the Arcannon. The Arcannon then casts a magnified version of a spell meant to target entire ships.
