Flairon

The Flairon is a melee weapon that auto-fires a ball-and-chain about 25 tiles from the player, and releases homing bubble projectiles that damage enemies. The Flairon has a 1/5 chance of being dropped by Duke Fishron.

Although graphically resembling a Flail, the Flairon is more similar in function to the Chain Knife, Harpoon, or Golem Fist. It is not affected by gravity, does not remain deployed when holding the fire button, and cannot be swing around. Rather, holding the fire button causes it to auto-fire repeatedly, returning and re-firing when it impacts or reaches its maximum range.

Tips

 * Because the Flairon produces the bubbles while it is being swung, it is much more effective if aimed just away from desired targets. The bubbles do the same amount of damage as the main projectile, but have the additional bonus of homing and frequency.
 * Traveling away from a returning Flairon can increase the duration of its bubble production. With enough movement speed, a player can produce bubbles continuously by continuing to move away at the same rate the Flairon is attempting to return.
 * The Flairon is effective against Duke Fishron. You can rely on the homing bubbles to take out its projectiles and the main boss itself while focusing on dodging, and still kill the boss relatively fast.

Trivia

 * "Flairon" seems to be a portmanteau of the words "Flail" and "Fishron".
 * The developers have referred to the Flairon as the "Flailron," suggesting that "Flairon" is an unintentional misspelling that may be fixed in a future version.
