# Achievements

The Achievements system lists all sorts of in-game stats and achievements. Some are related to exploration, others to gathering, combat, arena achievements, devotion and many more…

### Cards!

Some achievements give the right to a card linked to the player who is part of a family yet to be completed.

Ex: Picking up an emerald gives the achievement and the card <mark style="color:yellow;">\[Holder of an emerald]</mark> and this card is part of a family of cards called <mark style="color:yellow;">\[Precious stones]</mark> made up of 4 cards.

When a player completes a collection, the data of the big machine is updated and the latter grants a reward. It can be skins, bosses, $MTCB, items…
