Red candles can damage or destroy green ships and vice versa. Wicks will damage ships once it touch the edges or wing fins. Wicks will destroy when it cuts through around the middle. Candle bodies will damage ships if it barely touches the edge of the fuselage but will destroy once is cut a good portion of the ship or touches the wing fin. If candles shoot pass a fleet, ships in the timeline there after the fleet will join the opposing fleet.
