About this project
What does Necronomicon (Einsargen) add?
Necronomicon
Necronomicon adds a necromancy grimoire that allows you to assemble custom combat constructs from body parts of slain creatures and summon them into battle using bones.
Features
- Anatomical research: slaying any mob (except bosses) unlocks its anatomy in the grimoire. Supports 34 vanilla mobs along with dynamic support for third-party modded mobs.
- Interactive 3D grimoire: the book interface displays a live 3D preview of the construct, recalculating total health, damage, movement speed, and active abilities whenever a body part is changed.
- Modular assembly: 4 slots (head, torso, arms, legs). Constructs preserve the natural scale and shape of donors (quadrupeds retain 4 walking legs; large and elongated creatures maintain their world proportions without shrinking into humanoids).
- 11 passive abilities: flight, poison, wither, ignite, slowness, lifesteal, regeneration, fling, teleportation to targets, explosive death, and tough hide (damage resistance).
- Summoning and control:
- Right-click opens the grimoire with a direct summon button.
- The
Crouch + Look down + Right-clickgesture instantly summons the assembled minion without opening the interface. - Summoning cost scales from 1 to 8 bones based on the minion's total power.
- Owners can damage their own constructs or dismiss all active minions at once through a double-confirmation button in the book.
Compatibility
When installed alongside Einsargen, the standalone mod's recipe and item automatically yield to the Einsargen Necronomicon, preventing duplicate items and conflicts.
