Missions

Missions is one of the progression systems in DHC. It offers decent rewards for completing certain tasks. Each page of missions corresponds to 1 adventure board. 7 boards x 3 difficulty levels = 21 pages of missions.
==Missions? Achievements? What's the difference?==
The difference between missions and achievements is that missions are task-based whereas achievements are milestone-based. A mission might ask you to defeat the Elder Drake a number of times at any level, while an achievement will require you to defeat certain levels of the boss.
It is also important to note that achievements progress altogether, whereas missions progress one at a time. This is a very important distinction especially for later missions such as leveling a champion to 60. If you did it before that mission is unlocked, you may get no mission progress for a long time. 
Hence, it is wise to scout a few boards ahead to see if there's something you should save for later instead of doing it now.
