There are 18 challenges during the event, allowing you to earn 7 million points every week for 3 weeks.
To face the bosses (from Stage 1 to Stage 3), interact with the Shivering Snowman (NPC) who spawns before each Chapter's Final Boss, in the Preparation Room.
In the Snow-covered Mountain, if you are hit 3 times by a Snowman Boss, the challenge will be considered failed, but you can spend gold (increments of 500, starting at 500) to try again.
Each time you retry, the number of times you can get hit before the Stage fails increases by 1 (i.e., 5 hits possible when retrying 2 times: 3 + 1 + 1).
Only the highest damage dealt to a Stage Boss will be counted towards the event score.
Each time you defeat a Boss, you can challenge a higher level one (Stage 1 → 2 → 3). If you fail to defeat a Stage Boss, you will face it again in the next Chapter.
In the event that you are still facing Stage 2 in Chapter 04, upon defeating the Stage 2 Boss, you will be allowed to face the Stage 3 Boss immediately after returning to the Preparation Room.
0.5 HP X (number of times you are hit) will drop from the reward box (MAX 3).
Relics will drop from the reward box in proportion to the amount of damage inflicted on each boss.
Snowman points are awarded based on the highest score earned during the day. If you get 20,000 points in the first dungeon and then 70,000 points in the second dungeon, only 70,000 points will be recorded. If you kill all the Snowmen in stages 1, 2, and 3 in Challenge Mode Stage 8, you will no longer be able to earn points that day.
If your cumulative score exceeds 100 million points, you can obtain 1 gem for every 100,000 points of your cumulative score on that day.
The Stage 1 and Stage 2 Bosses are similar in terms of attack patterns, with the only difference between them being the amount of HP the Bosses possess.
Stage 3 requires the Player not to be greedy. The Boss delivers multiple slams and swipes in quick succession, and the Player should be careful not to get hit. Time your attacks well and focus on survival.
