Flying pig event

[Peasant]

Hi, so i've encountered a flying pig which i fed adena, then killed and got some pretty cool loot. Couldn't find any info about it on your site/forum. Could someone tell me how do they spawn - is it random or it spawn for you when you farm mobs, etc? More info, thanks.

Lucky Pig

While hunting in certain zones, you can encounter the Lucky Pig. (It has replaced the Fortune Bug.) Lucky Pig is a flying pig with white feathery wings. When it appears, it shouts and approaches a nearby character at random.
Lucky Pig eats Adena dropped nearby and disappears if not fed for 10 minutes. You can feed Adena to Lucky Pig a minimum of three times and a maximum of ten times. Talk to it to determine if it's full. When it is full, Lucky Pig loses its wings. At that point, it may give you a reward for feeding it.
You can obtain a reward either by feeding Lucky Pig ten times or talking to it after you have fed it at least three times.
Lucky Pig Locations:

    Level 52 Lucky Pig: Enchanted Valley.
    Level 70 Lucky Pig: Forest of the Dead, Valley of Saints.
    Level 80 Lucky Pig: Wild Beast Pastures, Plains of the Lizardmen, Sel Mahum Training Grounds, Fields of Whispers & Silence, Crypts of Disgrace, Den of Evil, Primeval Isle, and the solo area in Dragon Valley.

Lucky Pig Rewards:

    Level 52 Lucky Pig: Neolithic Crystal B and Top-Grade Life Stone - Level 52.
    Level 70 Lucky Pig: Neolithic Crystal A and Soul Crystals - Stage 11.
    Level 80 Lucky Pig: Neolithic Crystal S and Attribute crystals.

You can exchange Neolithic Crystals with a Dimensional Merchant to change a normal weapon into a rare weapon. (Dimensional Merchants are now functional.) To change a weapon into a rare weapon, you need to supply the Dimensional Merchant with the weapon and 1 Neolithic Crystal of the same grade.
