Fight Overview

For all 3 modes at The Great Olm, the boss fight will remain the same. Upon entering the room there will be a portal. Going through this portal will initiate the fight and The Great Olm will spawn in 30 seconds. When doing Challenge Mode, the leader can wait in this room until all members of the party are inside before going through to portal to start the fight. The hand to the left of Olm's head(named "Great Olm (Right Claw)") must be killed with a Magic weapon. The hand to the right of Olm's head(named "Great Olm (Left Claw)") must be killed with a Melee Weapon. The claw weak to Magic must be killed first, if the claw weak to Melee is damaged before the other claw dies it will defend itself and stall the fight for a few seconds. After 3 phases, The Great Olm's head can be killed. This will end the fight and grant the player their reward. Olm's head does not require a specific combat style. Fight Mechanics: Crystal Burst: Olm throws a crystal seedling under every player in the chamber. A few seconds later, the crystals burst and shove the player to a nearby tile if they are on top of them for heavy damage. The left hand will briefly show a crystal icon when using this attack. Swap: Olm will perform a teleport attack that deals damage the further the player is from the target. If alone, Olm will pick a random tile anywhere in the chamber; if there are more players in the room, Olm will evenly distribute the amount of teleports. If there is an odd-numbered amount of people inside, then those people will not be subjected to the attack. Lightning: Shoots out lightning running north and/or south of the chamber. Getting hit by a bolt of lightning electrocutes the player, disabling their overhead prayers, dealing moderate damage, and binding them. Acid Drip: Olm covers a player in acid, causing them to generate acid pools under them. Standing still will deal damage and moving will generate more pools. Deep Burn: Olm shoots out a green fireball at a player, causing them to yell "Burn with me!". The targeted player takes 5 damage every few ticks, dropping stats by 2 each time this occurs for six hits. If it spreads to other players, the timer resets and newly infected players will initially yell "I will burn with you." Fire Wall: Olm shoots out two walls of fire at a player to trap them. If the player is on a tile that would be occupied by the fire wall, they will leap out and take 8-10 damage in the process. After the walls are placed, players in the tiles between the two walls will take 50-65 damage in 5 seconds if they do not escape. Falling Crystals: During phase transitions and the last phase, Olm causes chunks of crystal to fall from above. These crystals have a 3x3 AoE; getting directly hit (underneath the shadow) by them will deal 16-25 damage, while getting indirectly hit (one tile from centre) deals 10-16 damage. One crystal will always be aimed at a random player in the chamber. A shadow will indicate where the crystal will land. If caught within multiple crystals AOE, these are capable of dealing massive amounts of damage.
