|Gorlach and Bouldergut are a single encounter.|
Sixth boss of the Infernal Dawn 20 man raid instance released April 2012 along with patch 1.8.
Considered to be the hardest encounter within the instance with a high focus on awareness and with a very tight DPS check.
The fight it self consists of three different phases all characterized but the need for energy draining, a mechanic never seen before in any other raid encounter in Rift.
