Comparing to Auto Chess the economy in the game remained the same, but Valve changed and simplified the system of objects. In Underlords, artifacts do not fall from dead creeps, but are issued after each round. The player can choose an item or one of the two proposed bonuses for races and classes. Units can have only one artifact, but they can be freely shifted.
Among the items were both familiar to Auto Chess, and those that are not even in Dota 2. The first give about the same bonuses as in the game from Drodo Studio, and get to know the rest before the start of the match. For example, you can find a passive effect that allows you to add an additional figure to the field.
