To unlock the Konsumed trophy in Mortal Kombat 11, you will need to use 100 Konsumables, which are modifiers and buffs, in the Towers of Time.
You will also unlock the trophy below when you use 50 Konsumables:
You earn Konsumables in the Towers of Time and from opening Krypt chests. Once you have some, from the Main Menu > Konquer > Towers of Time. Make sure you use Konsumables in every match.
Once you have used 100 Konsumables, the trophy will unlock.
