Pot o' Gold

The Pot o' Gold was a pet item used to summon Leprechaun o'Fyffe. The Leprechaun had a chance to drop coins when it jumped. It usually dropped Copper Coins, but had a chance to sometimes drop Silver, Gold, or even Platinum Coins. The 5 Rainbow Pieces needed to craft it used to fall from the sky during the season.

Trivia

 * Despite the fact that it was called a Pot o' Gold, it had no sell value.
 * It was possible to farm his coins by making a room with a low ceiling, having o'Fyffe on one side of the door and the player on the other. He would try to jump out (probably because he thought it is simply an obstacle). If the player placed a block above his head, he would jump even faster as he could fit through a 2 block gap. Being too far away would cause him to fly through blocks toward the player.
 * Fyffe means money in Finnish slang.
