Forms Quests

Step 1: Darkness Awaits
Head directly east from Khal along the road to Raia Village. You are looking for the field of bones, which is easy to pick out from the giant rib cages protruding from the ground. There are a bunch of hyenas and vultures there during the day. At night the Restless Spirits will spawn. By level 30 you can easily kill them since they were around level 10. You need to collect 5 essences off these mobs. The drop is fairly common but not 100%. I have to kill six to get my 5 drops. Return to Dulmier Shurdelra.

Step 2: The Depths of Sorrow
This quest asks you to speak with the dead guard’s spirit on the docks. I’m unsure if Guard Duhamel is up during the day. The quest would suggest he, like the Restless Spirits in Step 1, is only up at night. He wanders the docks. I found him almost directly across from the spell trainer area, on the other side of Khal. You have to pass through some lengthy dialog from Guard Duhamel. When you have progressed through it all, return to Dulmier Shurdelra.

Step 3: The Meaning of Death
Dulmier Shurdelra explains the two choices you have, Form of Bones and Wraithform.

Form of Bones will make you look like a skeleton, adds armor class and hit points. It also boost the damage you do with bone and poison spells, which include Bone Spear, Bone Spike, Detonate Corpse, Plague of Infestation, Poison Burst, and Sealed Fate.

Level 30: +122 to armor class, +15% bonus to damage with physical and poison spells, +10% hit points
Level 40: +125 to armor class, +20% bonus to damage with physical and poison spells, +20% hit points
Level 50: +166 to armor class, +25% bonus to damage with physical and poison spells, +30% hit points
Wraithform makes you look invisible with a green tint and gives you a rune to ward against damage and levitation. It also increases the damage you do with spiritual spells, which include Dark Rebuke, Devouring Shadows, Drain Life, Life Draught, Shadow Feast, and Torment.

Level 30: +15% to spiritual damage, levitation, 8% damage rune
Level 40: +20% to spiritual spell damage, levitation, 10% damage rune
Level 50: +25% to spiritual spell damage, levitation, 12% damage rune
Note: Both forms grant Enduring Breath and See Invisibility.

Talk to Dulmier Shurdelra again when you are ready to make your choice.

Step 4: Form of the Wraith
I chose Wraithform. Upon choosing wraith you will be given an item to summon a 3 dot lvl 30 creature called High Reaver in the Temple of Dailuk (susceptible to Fear and easily soloable). He drops some skin which you take back to Dulmier Shurdelra, who then gives you the wraith form. To find the spot to summon High Reaver, go to the northwest summoning circle in ToD. It is a circle of skulls on sticks, but it has to be the correct one for the quest to progress.

Manual of Unspeakable Deeds
Regardless of the form you choose, you also get a book to study at 3 different levels. The ability to study is under your general tab. Each minion you learn takes the spot of a normal minion and lasts the same amount of time. Below are the things Necromancers learn from the Manual:

Lich
Level 30
Plague Bringer’s Ritual - Summons a minion who will cast a debuff on your target increasing physical damage by 10% and decreasing physical resists by 240 (does affect melee damage slightly). The pet itself seems to do no damage.

Level 38
Ritual of the Servant - Summons a minion that occasionally heals the health of you and your party. Again, no damage dealt to target.

Level 46
Advocate’s Ritual - Summons a ghostly zealot who does tremendous damage versus undead mobs.

Wraith
Level 30
Plague Bringer’s Ritual - Summons a minion who will cast a debuff on your target increasing spiritual damage by 10% and decreasing spiritual resists by 240. The pet itself seems to do no damage.

Level 38
Wraith - Ritual of the Servant - Summons a minion that occasionally heals the energy of you and your party. Again, no damage dealt to target.

Level 46
Advocate’s Ritual - Summons a ghostly zealot who does tremendous damage versus undead mobs.
