The Great Olm is the final boss in the Chambers of Xeric raid.
Standard attacks: Olm has two standard attacks: Magic and Ranged. The magic attacks are large green orbs, while the ranged attacks are smaller chunks of crystal. Both deal the same amount of damage. Prayer reduces the damage by roughly 75-80%.
Spheres: Olm randomly picks a sphere (red, green or purple) and sends it at the player. If not blocked, the player will be damaged approximately 50% of their current Hitpoints. If a protection prayer was used when the sphere was launched, it is disabled and the player's Prayer is reduced by 50%. To block the attack, pray accordingly before and as the sphere hits you:
During phases 1-3, Olm also has access to these specific attacks:
Olm also has phase-unique attacks which can replace one of the auto-attacks in his rotation:
There are also attacks applied during other segments of the fight:
Olm has at least four phases, with an additional phase for every 8 players in the raid. Unlike the other bosses in the room, once the player enters his chamber, it is a fight to the death. In each phase except the penultimate and final ones, Olm will focus on a specific set of abilities referred to as powers.
Like other bosses in the chambers, many of Olm's stats scale between its claws and head depending on the stats and amount of players in the raid, despite him having a pre-determined combat level. Monster Examine can be cast on him. In most small teams, his combat stats and max hit are comparable to God Wars Dungeon bosses. If stat draining attacks — such as dragon warhammer special attack — are used, they only affect the part of him that was hit. His stats also reset when a new phase starts.
Olm attacks with ranged and magic, the former consisting of a chunk of crystal and latter green-coloured dragonfire. Olm has three attack zones to choose from; left, middle and right. He prioritises the zone with the most amount of players. If no players are in that zone, he will swerve his head accordingly and skip an attack in its attack rotation. If a player is in his attack zone but Olm swerves his head regardless, no attacks are skipped.
Olm's attack rotation consists of the following below. Phase-specific attacks are incorporated into the attack pattern as an auto-attack and alternate between the available pool:
In order to progress to the next phase, both of Olm's hands must be disabled. Olm's head can be attacked at any phase, although he will automatically recover any damage taken shortly afterwards in all but the final phase. When both hands are disabled, Olm will retreat underground and shake the area with AoE falling crystals before reappearing on the other side with a new power. During the penultimate phase, the left hand gains a damage to health ability indicated with an infinity sign on it. In this phase, both of Olm's hands must be disabled within a specific time frame or it will recover back at full health. All powers are available to Olm during this phase, and it is indicated with Olm's head glowing.
Once both hands are disabled, Olm remains on the spot and attempts a final stand. AoE crystals will continually fall from above until Olm is killed. As with the previous phase, he has access to all of its powers.
The Great Olm is located inside the Chambers of Xeric.
The Great Olm has no direct drops. Players are able to loot the Chambers of Xeric reward chest after defeating him.
Your gear and inventory will depend on the exact setup that you take into the Chambers of Xeric. Use your best Melee, Ranged, and Magic gear here. There must be at least one player in your raiding party who can deal damage from each of the 3 combat styles.
