He appears in the game as a skeletal[[Demons|Demon]], floating, legless apparitiona [[Superuniques|SuperUnique]], and possesses powerful magics to complement his physical attacksan [[Act Bosses|Act Boss]].
Despite these advantages, Mephisto is the most popular "monster run" in the game, since he is not that difficult to reach or kill, and he drops a lot of very high quality items. Item running Meph was made more difficult in v1.10, when Durance level 2 was greatly enlarged and made more random, but dedicated item runners still make Meph the backbone of much of the mid-level Diablo II economy. Hell Mephisto can not drop the highest level items, but he's a great source of all exceptional items, and most of the low-to-mid level elites.
Mephisto's skills:
* Lightning
* Charged Bolt
* Poison Nova
* "Skull" Missile
* Frost Nova
* Blizzard

A popular way for ranged attackers to defeat Mephisto is to use the blood moat against him. Lure him to the edge of it, then move back into the open area at the start of the level so Meph remains just at the edge of the screen. He will pace around in a small area, able to see you but unable to get any closer, and slowly succumb to arrows, bolts, spells, thrown weapons, or other such attacks.
