How do you get leprechaun class in aqw?

Leprechaun Class in AQWorlds is from the game's first ever St. Patrick's Day in 2009.

Leprechaun Class was dropped from the quest where you get Leprechaun Armor.

This class is rare now (like Alpha Pirate) and only appeared once in AQWorlds.

If you want something like leprechaun class just equip Leprechaun Armor (or Evolved Leprechaun Armor) and a class with rogue skills (like Pirate, Rogue, Barber, etc.).
