Four Weapons from Terraria.
The Star Cannon for Terraria (as of 1.1.2)
It fires a star every 150 ticks, about the same speed as in Terraria.
This star can pass through
multiple enemies what you are directly up against but gets blocked by everything else. .
I have taken care to ensure that it is exactly the same as the one in Terraria,
inclusive of sounds.

In the real game, just for comparison.

Shoots Laser Beams at 300000 muzzle velocity and with a 0.0000000001 tick delay between them.
Each shot does 9 damage.

DUAL RELEASE: SPELLS
Crystal Storm + Magical Harp, for bouncing-around-corners needs.
The Magical Harp, sadly, cannot pass through people. Blame Torque Engine.
