Last Updated: Release 27.7.X11.1
The Leprechaun spawned for St. Patricks Day 2017. He always dropped the Rainbow Road.
A different varient of him spawns for Month of the Mad God 2017, which may drop the Pot of Gold directly, or the Rainbow Road very rarely.
May drop a:Pot of Gold
May also drop a:Rainbow Road
Only spawns once per realm as a quest, making it essential to be in a fresh realm to find one. When the Leprechaun is still alive you can see two different quests as red dots on the minimap (but only the closest quest icon). If the closest quest to you is a different monster, that means the second red dot is the Leprechaun.
The Leprechaun is extremely fast and it is impossible to kill him without a lot of speed or a slowing item. Best strategy is to have a warrior/ninja rush towards him and try to corner him in the dark water so he cant run. Cornering him in other structures works too. Once you corner use Archer or Huntress to slow and attack. It is not stasis immune so a mystic is a plus. Repeat until he dies. Once dead he will drop a portal to Rainbow road or spawn a Pot of Gold.
Slowing the leprechaun helps a lot. It is however, immune to paralyze, so try to get as many slows in as possible.
An archer/huntress can slow the creature, but it is hard to aim (especially with a quiver). A Paladin with a Seal of Enchanted Forest can help slow the leprechaun down, and is generally more effective then a quiver, as the seal uses radius instead of a single shot. The Scepter of Fulmination also helps, as it doesn’t need much aiming.
When you do slow the leprechaun, try to have a group surround the monster, and shoot at it.
Last Updated: Patch X.16.2
The Leprechaun Statue is the Month of the Mad God counterpart of the Leprechaun. the Leprechaun Statue is spawning for the rest of the Month of the Mad God 2017.
The Leprechaun Statue moves around similar to the Leprechaun, but can be caught fairly easily. It does not move extremely fast and is easy to catch even without a warrior, ninja, or slowing item, but is recommended to use. Once its health is lowered it will flash blue and its stone body will be destroyed. Then it will become its fast leprechaun form and jump very far across the realm. It will change locations about 2 times when players are halfway near the leprechaun

The Leprechaun Statue is not fast at all compared to the Leprechaun himself. (Click to see the Leprechaun’s information) The Leprechaun Statue can be killed fairly easily in a big group in a fresh realm. He still may be too fast for small groups, but does not skip through the whole map like the real Leprechaun does. When you kill the Leprechaun Statue, the real Leprechaun will spawn, which drops the pot or rainbow road that gives the loot. (Click to see the real Leprechaun’s information)
