In Atlantica Online, there's a Special Christmas event where a dungeon called Holy Town opens up in Norther Europe near Ostersund. Each hour a day, you receive a free ticket to get inside this dungeon for a limited of time. There, you will find an NPC who will give you these items as you complete the quests. Once the quests are finished, they will reset the next until the event ends. These items you earn can be used to trade with NPCs outside the dungeon for prizes you would normally grind or pay for such as a Mercenary Summon, a featured mount, a featured set of clothing, or some experience books to help you and your mercenaries level up.
This same idea applies to other events, especially during the holidays so those are your tickets to gaining a chance of winning free stuff. Participate as much as you can. But you'll get a better chance at gaining more prizes if you're at a higher level. Level cap in this game so far is 170. There's a chance that they might increase it further depending on what new dungeons they release.
By the way, if you want to play Atlantica Online, play it soon. The event is still up until January 18th. Rack up the prizes while you still can.
