Open Chests at the end of the Endgame Labyrinth 500

PoE Heist 3.12 challenge: Open Chests at the end of the Endgame Labyrinth 500.

Averagely, there are 5.5 chests in an Endgame Labyrinth. To complete this challenge, you may need to run about 91 Labyrinth. It may take you over 15 hours.

One Treasure Key is required to open each chest. Keys are found throughout the Labyrinth and from Izaro himself. During the first two Izaro encounters, players may choose to focus on Izaro without disabling his extra buff/damage mechanics. If not disabled these mechanics then carry over to the next phase of the fight making it more dangerous, but also more rewarding. Izaro will drop an additional key for each mechanic in place at the end of the fight. Additional Treasure Keys can be obtained by killing Argus or opening Curious Lockboxes.
