Saint Patrick

The Saint Patrick (Event) is a new event that went live on March 11, 2016. In a fashion similar to the Easter Egg Hunt events, the player must collect as much as possible, which sometimes appear when an enemy is killed, in order to progress through the event. You also have a chance to collect a lucky Pot of Gold that is worth as well ( if you bought the Double Gold Booster!).

Lucky Shamrock Multiplier
Normally, a player adds only  to his meter for every one picked. However, the update introduced two new bundles which both contain a head item that multiplies the  collected either by 2x or 4x. The Lucky Beret, from the Lucky Fighter's Pack, multiplies it by 2x while the Leprechaun's Hat, from the Leprechaun's Pack, multiplies it by 4x.
