Every 4th round, and on Round 1, players get to choose one item from a random select of three to add to their arsenal. Offensive, Defensive, Support and Hat items may be equipped on heroes, but not on Underlords or on heroes whose abilities do not support the item in question.
Contraptions are special items that may be placed on the field.
The choices for each Item Round can be rerolled one time. The 3 choices are blacklisted and will not appear again for the reroll.
Each selection, items have a percent chance to be from a specific tier. The item chosen from each tier is random.
The following is a list of every item in Dota Underlords.
