Stafford ' s the fucking man <| sep |> Okay , let ' s go through the rewards of Labyrinth onebyone . 1 . Treasure keys Depending on what and how you do the labyrinth , you can get anywhere from 15 keys . These keys are earned by completing the Izaro encounters on hardmode , as in deliberately ignoringfailing the mechanics , making subsequent fights with him harder . This way you ' ll earn 2 extra keys . One key can be gotten by killing Argus , found somewhere within the labyrinth . Sometimes there is a treasure chest intricate ? I believe in a silver room that rewards the last key . 2 . Item upgrade These item upgrades are called enchants . Everytime you complete the labyrinth , you can enchant a piece of equipment once . On normal difficulty , you can only enchant gloves . On Cruel , gloves or boots and on Merciless gloves , boots or helmet . 3 . Swirly effect I have absolutely no clue what this is . 4 . Ascendancy points First time per characters per difficulty you complete the lab , you can click the altar at the end to first choose your Ascendancy class and then receive further points into it .
