The Hemogoblin

140k hp goblin, is mainly heat and crushing with most attacks in the low 1k ranges. Spawns adds that have 25-35k hit points (usually 4-5 of these) that are also heat/crushing. They will attack the first target the name aggros.

If you don't pull the name out of the room with the blood, then even more adds with spawn in the 45k hp area and keep spawning as long as the name is near the blood (also heat/crushing).
