Vortex Vanquisher

The Vortex Vanquisher is a Hardmode Spear. When used, the first use stabs, the second use swings, the third use is thrown forwards and the fourth thrusts the player forwards, and holding it will instead thrusts the player forwards, firing down Vortex Vanquishers into the ground behind them. If, it summons a Stone Post and creates a shield around the player that increases immunity frames.
