Diablo II/Radament's Lair

Radament's Lair
This quest is triggered by the innkeeper Atma, who explains that a sewer-dwelling creature called Radament has been preying on the people of Lut Gholein, and that she has already lost her family to it. To begin the quest, enter Level 1 of the sewers via the trapdoor just up the street fom Atma. You'll encounter plenty of undead-type enemies, some of which can poison you, so be sure to bring some antidote potions along. You'll find Radament somewhere in Level 2 of the sewers, surrounded by numerous undead enemies, which he can resurrect. Kill as many as possible and work your way to Radament himself. Radament is a tough enemy, as he can poison you (with an incredibly long duration), and his minions tend to gang up on you while you're hacking away at him. You may have to use a few town portal scrolls, but if you keep attacking (and breifly retreating, if need be.), Radament will eventually fall, giving you acess to a treasure chest with plenty of rewards in store! After killing Radament, report back to Atma above the sewers.
