If you want to get a Free Evil Snake Lord hat, Just redeem 4000+ WP -> Kafra points by March 31st
In both above cases we will email you a code on the following Mon/Wed that you can redeem to your Ragnarok Account and pick up from the "Code the Redeemer" NPC.
As a special promotion we are giving Extra Free Kafra points when you convert WP points through 5pm
So you could redeem 2 UGC cards, convert the 4000 WP -> Kafra points and earn
2 Snake Hats, 1 Evil Snake Hat and get a few extra Kafra points!
Update: We are extending the WPE conversion event until April 1st noon. This is due to the person in charge of making the change back to default needs to leave early. And we figured most players wouldn't mind a promotion being extended another day so they could participate!
