Challenge Maps
For quests, see Quests, while for mission quests, see Mission Quests.
Challenge Maps are regular maps with modifiers applied to them, which increase their difficulty. It can be found in the Quests menu under the Challenges tab. Upon triumphing the map, players are rewarded with various rewards.
Mechanics[]

Challenge Maps do not require anything to be activated, other than having a level requirement of Level 50. Rewards from a Challenge Map can only be claimed once each week. Losing grants no rewards other than 0 EXP. Triumphing grants rewards that change based on the challenge.
One Challenge Map appears every week, resetting at 00:00 UTC on Sundays. The challenge is the same for each player.
