# Samples 2
Creature Ethereal Undead (ghosts, wraiths)
Ancient Ghost

The ingredient Ectoplasm can be collected from Ethereal Undead.



2 guaranteed samples can be found in the following locations:

It can also be found randomly in the inventories of alchemy vendors (starting at level 4) and in some Necromancer and Vampire loot chests (starting at level 4).


Ectoplasm is obtained from almost every type of Ethereal Undead creature, including standard Ghosts, Ancient Ghosts, Faded Wraiths, standard Wraiths, Gloom Wraiths, Sanctified Dead, and Spectral Sailors. These creatures are most commonly encountered in Undead Dungeons where, starting at level 6, there is a roughly one in three chance that any undead will be ethereal. Undead also spawn using the same leveled lists in Vampire and Necromancer Dungeons.

There are some locations that spawn only ethereal undead and therefore have greater probabilities of yielding ectoplasm and also allow ectoplasm to be located before level 6. These places are indicated on the map by red circles and include:

  • Sancre Tor has 26-30 ethereal undead (but can only be entered after starting the quest Blood of the Divines).
  • Rielle has 6 ethereal undead (2 more likely above level 6, based on probabilities for each creature to appear and be an ethereal undead).
  • Vahtacen has 7 ethereal undead (but the undead can only be reached after starting the quest Vahtacen's Secret).
  • Wendir has 4 ethereal undead.
  • Malada has 4 ethereal undead.
  • The undercrofts of the chapels in most cities contain Sanctified Dead, which are respawning ethereal undead creatures and can provide a good source of ectoplasm if you can gain access to the undercrofts (the Pilgrimage quest added by the Knights of the Nine makes all chapel undercrofts accessible; alternatively, the locks can be picked or opened using spells).
    • 5 Sanctified Dead are in the Great Chapel of Talos in Bruma
    • 5 Sanctified Dead are in the Great Chapel of Zenithar in Leyawiin
    • 4 Sanctified Dead are in the Great Chapel of Mara in Bravil
    • 4 Sanctified Dead are in the Great Chapel of Dibella in Anvil
    • 3 Sanctified Dead are in the Great Chapel of Julianos in Skingrad
    • The Great Chapel of Arkay in Cheydinhal does not contain any Sanctified Dead, although Llathasa's Spirit (non-respawning) will appear here during the quest The Elven Maiden
  • Several quests involve ethereal undead, although these undead will not respawn (magenta circles on map):
