**DISCLAIMER, THIS IS AN EDUCATED GUESS ON THE EVENT TYPE, IT IS VERY WELL POSSIBLE IT COULD BE A QUEST EVENT LIKE TEARS, MY PERSONAL BELIEF THOUGH IS THAT IT WILL BE A RAID EVENT**
Well, tis the season for another event, and this time it will be a stamina/hp event. It appears from the description that this event will follow the format of the Blizzard of the Crystal Castle. My reason for saying this is the words 'Collect as many boxes of toys as you can, and you'll get rewards based on your ranking! you can even get Boss Takedown Rewards and rewards for choosing the right paths!
The takedown rewards and the gathering of presents mirrors the take down rewards and gathering of shards from the Blizzard of the Crystal Castle. Also, since they can introduce new cards for boss damage during these events, they tend to be most profitable for them.
Now for those who don't know the event will follow a simple format.
Quests:
Players will progress through quests and randomly instead of a chest, a boss will spawn. A player is given a certain amount of time to destroy that boss. In this case, Ogre Santa and I'm sure the Wight King will make appearances. Players will receive rewards based on how much damage they do to the boss, these rewards are going to be presents and points. Presents can be traded for cards or items, similar to white/blue/pink/gold shards in Blizzard of the Crystal Castle.
Every five quests players will also have a normal quest boss to deal with. This boss will normally yield rupies and personal clear water or holy powder. Before you reach the boss you will have to choose a path, if you choose correctly you move to the boss, if you choose incorrectly you must go back to the previous quest.
Bosses:
The bosses summoned have varying degrees of health. During the last half of the event I'm sure we'll see the Wight King who will have a very large health pool. Players attack the boss using their attack deck, the more powerful the deck, the more damage. Using event cards with boss damaging skills also increases the overall power of the deck significantly and is very necessary for players who wish to perform well.
Upon taking down the boss, players are rewarded with presents. The presents can then be traded for items. The presents and points you receive are based on: Discovering the monster, damage done to the monster, critical bonuses at 66% and 33%, takedown bonus for killing him, and most damage done. Because of the critical bonuses, it is recommended that you attack every boss that appears at least once since you will be eligible for those bonuses regardless of how much damage you do.
Ranking Highly:
The best way to rank highly is going to be to pick up event cards early. The nice part is if you grab those cards early you can do heavy damage and receive a lot of presents while spending a smaller amount of HP. If this event functions like the previous, HP will be a possible reward from the presents. This means the you can do enough damage you could feasibly cycle through bosses by gaining the HP you spend back in presents.
You can also share cards with members of your orders if you are in different time zones. I know several players that did very well renting out their event cards to players for a few hours who then pounded through bosses to gain shards and points.
Overall though, the best results will be for people who participate heavily. Being on regularly to attack every boss once will yield strong rolling returns.
Odysseus and Zhuque:
If I recall, Odysseus's skill is called Ogre Slayer and he does a big boost to damage against Giants. Much like Ax Masters skill proc'd against Crystal Dragon because he was a dragon, it's fair to assume that Odysseus's skill will proc against Ogres. It might be worth picking up a couple.
Zhuque on the other hand confuses me because he only states that he does additional damage to Wight King in 'the puppet master'. This leads me to believe that he will not do additional damage to the Wight King in this event.
In both cases of these two cards I could be wrong, but given their low current prices, they would be worth picking up before people realize it.
