Beastmaster Durzag

SpiderMan is the first boss of the Liberation of Mazcab raid. He is an airut who has amassed powers greater than an airut normally would, along with the Shaman, according to the Fifth stone fragment.

SpiderMan can be looted once every 2 days for rewards including the superior versions of Teralith, Primeval and Tempest equipment. Starting the encounter requires challengers to form a raid group with the Grouping System to enter the instance.

The fight
SpiderMan does not appear in the fight initially; players must first free the goebie in the middle of the arena to start the fight. Once freed, a wave of enemies consisting of Chargers, Airuts, along with Cormes, one of Durzag's pets, will attack the group. Once all of them are cleared, Durzag will appear with one of his pets, either Krar or Tuz, before he calls for the other one. Chargers will also appear in small pens when this happens; these can be freed and killed to reduce/stop his swarm attack.

Krar and Tuz should be separated from Durzag, to reduce the amount of damage Durzag can deal.

Every wall also has a broken gong in it, which can be repaired; however it takes a while to construct when doing it alone. When Durzag is nearby, it can be rung one time only, decreasing his accuracy for a while and will deplete much of the player's prayer points at the same time.

Occasionally, he throws bombs, tiny-rocket like pig vehicles which attempt to follow a player before exploding. They deal 2,000 magic damage to nearby players upon explosion.

Rewards
Upon death, Durzag's corpse can be looted for various drops. The loot will be made up of the 100% drop, a consumables item and one of: several standard drops, an ability codex, or a piece of armour. Durzag's corpse can only be looted once per 48 hours.

Unique drops
Durzag can only drop one item from this table. If no armour piece or ability codex is dropped, the player will receive teci.

The drop rate of any piece of Achto Primeval, Tempest, or Teralith equipment is gradually increased (up to twice as common of a drop rate) based on how many pieces of a regular Primeval, Tempest, or Teralith equipment set a player has purchased from the Goebie Armoursmith. The purchased pieces may be of varying equipment types, but must constitute all five parts of an equipment set. Armour is always obtained in the same order: Boots, gloves.

Trivia

 * Durzag's examine references the cliche "As blind as a bat". His blindness comes into play in the fight mechanics as he loses accuracy when his pets cannot guide him towards the enemy and when the gongs impair his hearing.
 * Durzag's drop table, along with Yakamaru's, were greatly increased after player complaints of the rewards being too low for having to wait 2 days to be able to loot again.
