Mephisto (Demon)
Mephisto was the first Prime Evil to be captured and his stone
was buried in a vault beneath the Aranoch desert. A third of the
Horadrim stayed to guard this tomb until the remaining two Brothers
were captured. Though the cost was high, all of The Three were eventually
captured.
Mephisto finally managed to overcome the powers of the Soulstone
that imprisoned him enough to influence and corrupt the local priesthood,
known as the Zakarum. The Demon then had the priests work spells
to shatter the Soulstone into seven shards, breaking the mystic
seal and freeing the Lord of Hatred. Mephisto drove the six smaller
shards into the left palms of six Zakarum archbishops who were then
charged with bringing him nourishment in the form of human sacrifices
while running their temple. The largest stone pierced the hand of
the Que-Hegan, the highest divine authority of the Zakarum faith.
It was this body that the Demon used as his manifestation on the
mortal plane, warping the mortal’s form into an approximation of
his true visage. For years the corrupted religious leaders of the
Zakarum have kept Mephisto supplied with information and misguided
followers to carry out his plans of conquest.
Tips and Other Additional Information
Clear out any nearby Council Members or monsters in the area. If you're
unable to kill some of the Council Members you can use this trick:
open up a Town Portal in the middle room with Mephisto or the left
room. Then lead any Council Members you're unable to kill to the stairs
that lead to Durance of Hate Level 2. Now run back to the Waypoint
in Durance of Hate Level 2 and use it to go back to Town. From Town
enter your Town Portal and you'll be back in Mephisto's Lair. The
Council Members will be back at the stairs out of the way, if you
lead them away correctly and placed the Town Portal far enough away
from the stairs. You'll now be able to attack Mephisto without his
being helped by those council Members.
Cold and Lightning Resistance helps a lot against Mephisto.
Mephisto uses the following Skills: Lightning, Charged Bolt, Poison
Nova, "Skull" Missile, Frost Nova, Blizzard.
