The ancient chest is found in the Great Olm's room in the Chambers of Xeric raid, and can be searched for rewards after defeating the Great Olm.

If you leave the Chambers without looting the reward chest, the game warns you that you will be abandoning your loot. This is inaccurate, as any unclaimed loot is placed in the storage unit outside. Opening the reward chest is not necessary.

Loot table

If multiple rolls on special items are successfully rolled, then the light will alternate between the available colours. Regardless of the light's colour, players will always find a dark journal inside unless it is stored in their bank.

Unique drop table

Upon the Great Olm's death, if a unique reward item is given, it will be announced in the game chat. The player who receives a unique drop will have the beam of light on their chest glow purple.

For every 8,676 total points obtained, a 1% chance to obtain a unique loot is given. If one of these items are received, no common rewards are given.

This chance is capped at 65.7% (570,000 points) - any further points will be sent to roll for a second unique loot. For example, a team who possesses 855,000 points in total has a 65.7% chance to receive a unique loot, and then a 32.85% chance to obtain a second unique loot.^[1] Up to six unique rewards can be obtained per raid, assuming that there are enough points to roll for them.

In groups, the player's points will also determine who is more likely to obtain the unique drop if rolled on, with higher points giving a greater chance at it.

Once the game has chosen which player will receive the unique loot, an item is chosen from the table below. The higher the weighting, the more likely a player will receive that item.

Common drop table

If no unique drops are rolled or not given to the player, they will make two rolls on the common drop table, and the light will glow white. Unlike the other two raids, the two rolls cannot end on the same drop.
