Treus Dayth

Treus Dayth is the boss monster in the Haunted Mine quest. He has the power to possess objects around him and send them hurtling towards players. He is summoned when the player attempts to pick up the Innocent-looking Key.

Treus Dayth is fight-able as a class G boss monster in the Dominion Tower minigame if the player has completed Haunted Mine.

He uses these three main attacks:
 * Crane-When you step in a square around a possessed crane, it will take a snap out of the player. It rarely hits above 100, but can hit in the low 300s. This is the second most dangerous attack out of three.
 * Mine Cart-When a player steps on a cart track, a mine cart will be sent tumbling after them. This hit damage of up to 90 damage every half second, which can equal to 360 damage every 2 seconds if you're unfortunate. This is the most dangerous attack.
 * Pickaxes-If the player is not near any other obstacle, Treus Dayth will simply make pickaxes appear and be shot at them. These hit up to 150 damage each, and cannot be blocked by the Protect from Missiles prayer, however it does weaken the damage taken. Pickaxes are the least dangerous attack.

Treus Dayth's imprisonment
Drakan had the abandoned mine destroyed after the holy River Salve started to seep into the lower shaft of the mine. Although most of the water was tainted by the land's twisted soil, some remained pure and retained Saradomin's blessing. Purple crystals were growing in the mine and absorbed the blessing. When exposed to the unholy creatures of the land, the crystals would severely weaken or even kill them. To prevent the crystals from falling into the hands of Saradominists, Drakan then imprisoned Treus Dayth, who was one of his followers, to guard the crystals on the lowest level. Even after Treus Dayth died, his tortured soul continued to serve as the mine's guardian.

The crystals are known to players as the Salve amulet or Salve amulet (e).

Strategy
Treus Dayth has a nasty habit of teleporting in spots where the machinery can hit you. All that needs to be done is look where he is standing, and carefully walk around equipment to get to him. The QuestHelp recommends attacking him with range or magic.

Habitat

 * Abandoned Mine

Trivia

 * Treus Dayth strongly resembles a Spectral Vyrewatch, which appears after a Vyre corpse is cremated. Treus may have been a Vyrewatch himself, but he died a troubled death under the hands of Lord Drakan (rather than a peaceful death via cremation), which may explain his slightly warped appearance.
