Abomination

The Abomination is the mutated form of the dragonkin Tarshak, and the final boss of the Hero's Welcome quest. It can be found in Tarshak's sanctum in the Brimhaven Dungeon. Its second form may be fought again after the quest by using the "refight" option on the Bane ore rockfall.

Players should be aware of the rapid damage that can occur when standing in fires, as well as the heavy damage from rocks falling from the ceiling.

Players can however use these damage sources as an advantage as the rocks and fire will also damage the Abomination. It is useful to lure the Abomination towards fire sources while these are active due to the fact that these will do damage for a certain time period.
