Trials

Chaos Trials are "playlists" of maps, by choosing to play Chaos Trials players will have to complete random map from set of 5 one by one. Each chaos trials tier have different set of maps, they do not rotate, but spoke about some kind of rotations in the future in one of Dev Streams. After getting item upgrades in Campaign, only way to get better items (and Shards is by playing Chaos Trials), if players will succeed in beating 3 maps, on 4th win and all subsequent wins, players will be awarded with additional Shard from difficulty they are playing.
