Necromancy is the final Sorcerous art, practised only by the greatest Necromancers and Sorcerers of Avalon. To gain Necromancy, the Sorcerer must pay a visit to Count Bezejeth who dwells inside the mansion of the Bedillam Forest, just off the Parrian highway. Bezejeth does not take kindly to visitors, though, and unless you boast an evil or bad alignment you should steer clear - the Count will simply slay those he does not like.
To gain Necromancy from Bezejeth, you must prove your worth to him. To do this you will be required to slay one good individual of the level Avalonian, and lay the dead body before Bezejeth, besides the corpse of Wykoshia, high priest of the Azrilites. You will also need to have attained the skill rank of Ultimate in both your Evocation and Demonology skills, and to have attained the alignment of Diabolical.
When you have satisfied these four criteria you should KNEEL before Bezejeth and he will bestow upon you the gift of Necromancy. Undertake the path of the Necromancer not lightly, though, for the price to pay is a great one.
