A hard task from Efiilas camp said that I need to kill an entelodont:

Kill an Entelodont
Our hunters have heard strange, and concerning, rumors about a beast known
only as the 'Entelodont'. We know very little about it, save that it's a kind
of massive carnivore that can rip a lion, drake, or trained soldier apart in
seconds. See if you can find and slay one, so we know what the hell we're
dealing with.

There is one in Valley of the Kings and I proceeded to check it out. It was taking damage from my skills and I got it to 90% after a few runs, so I decided to try to solo it completely.

The entelodont was hitting somewhat hard (about 200..250hps/round), so I had to get my eqs for it (I usually solo naked without eqs). With the eqs, I got the thing killed in about 20 minutes.

The entelodont kill is one of my rare over 100k solo kills:

Usually 100k+ monsters simply hit too hard, shoot something nasty, or regen too fast to be killable by a small monk.
