Love Potion
Love Potions drop from monsters you hunt. The Love Potions double P. Atk./M. Atk./Attack Speed/Casting Speed for 2 minutes for everyone in your party and change the appearance of your weapons. The Love Potion buff instantly activates upon pickup from defeated monsters.
(The effect of the Love Potion disappears when you restart the game.)
Coco Brownie (Event NPC):
Talk to Coco Brownie in any town to receive special Valentine’s Day buff items. You can choose Chocolate Truffle, Candy Heart, or Comfort Cookie. Each one slowly replenishes your Vitality in peace zones and also has its own special power.
You can only claim one type of buff item from Coco Brownie. Each buff lasts 2 hours, but there is no limit on usage. To receive a different type of buff from the NPC, delete your existing buff items in your inventory and choose again.
If 3 people in a party with each item gather around and use their buff items, they can receive all of the effects.
Example: Character A consumes the Chocolate Truffle, Character B consumes the Candy Heart, and Character C consumes the Comfort Cookie. All three buffs will appear on the status bar of everyone in the party.
