Mort Flesh is obtained from almost every type of Zombie Undead creature, including standard Zombies, Headless Zombies, Dread Zombies, Zombie Guardians, Motierre Zombies, and Mucianus Allias. The one notable exception are Deranged Zombies, which drop a special variety of Bonemeal instead of Mort Flesh. These creatures are most commonly encountered in Undead Dungeons where, starting at level 4, there is a roughly one in three chance that any undead will be zombies. Undead also spawn using the same leveled lists in Vampire and Necromancer Dungeons. There are some locations that spawn only zombie undead and therefore have greater probabilities of yielding Mort Flesh and also allow Mort Flesh to be located before level 4. The places where respawning zombies are guaranteed to appear at all levels are (red circles on map):
- Culotte has 6 zombies (although they only appear after you have explored most of the dungeon)
- Kemen has 4-5 zombies.
- Lindai has 4 zombies, and another 5 standard leveled undead.
- The Old Way has 3 zombies (8 likely), but can only be accessed during The Ultimate Heist quest.
- Ninendava has 2-5 zombies.
- Amelion Tomb has 2-4 zombies, and another 2 leveled undead.
- Mackamentain has 2 zombies.
- Underpall Cave has 1-5 zombies.
- Howling Cave has 1 zombie.
Places with non-respawning guaranteed zombies are (magenta circles):
- Miscarcand has 19 nonrespawning zombies.
- The Chorrol Chapel Undercroft contains 3 Motierre Zombies as part of The Assassinated Man quest.
- Mucianus Allias is found in Nenyond Twyll during the quest Liberation or Apprehension? (although with his unusually high health, it may not be worth killing him just for a sample of Mort Flesh).
- The Tutorial dungeon contains 1 zombie.
