File:Undead Mammoth Beast (Riposte).gif

Summary
The Undead Mammoth Beast is an intimidating boss, and can really deal out some damage, if you like to play with low sanity. However, its riposte openings are pretty simple, and you can even block the charges it launches at you, regardless of if riposte activates, or not. It is additionally INCREDIBLY weak to bleed damage, if you have a set up that can maximize that particular damage type. The Organ, above where you fight Tristana in the Gardens of Mornia, is an excellent (and really fun) option.
