The infernal abyss dungeon is the T4 dungeon. Inside you face many bosses and it is packed full of T4s that have anywhere from 8k to 11k hp. Upon finishing, you are rewarded with either a piece of Unique T4 Armor of very high quality, or a T4 staff that can hit 200s. While on the map it appears to be the TNT Filled Cave, it is actually underground at the back of a cave accessed farther north.
