Luck effect can affect most of the Chest loots now.

New Features

Luck/Bad Luck have additional features now:
An 'Unsei' system is now added: players shall be divined, a level of Luck or Bad Luck will be given randomly everyday.
New combact modifications :Luck will enhance a player's attack or critical rate; whereas Bad Luck will reduce a player's hit rate, and there will be a higher possibility that a player's shield will be disabled.

New Items

Several items related to the luck are now added, you have to collect four-leaf clover as an ingredient before crafting the items.
You may get a four-leaf clover by breaking grass, not fern(with occasional chance just like how you find it out in reality).
