Mob Amputation Mod 1.12.2, — Reference
Core Mechanics
The primary mechanic of the mod is the Amputation Chance. Every time a player strikes a supported mob, there is a randomized probability that a limb (arm, leg, or head) will be severed. This chance is heavily influenced by the type of tool used.
Tool Efficiency Tiers
Different tools have varying success rates for amputation. Generally, edged weapons are the most effective.
| Tool Type | Amputation Success Rate |
|---|---|
| Swords & Axes | Highest (Default ~90% in some versions) |
| Pickaxes | Medium |
| Arrows & Fishing Hooks | Low |
| Spades (Shovels) | Lowest |
| Bare Hands / Other Items | Zero (unless configured otherwise) |
Headless Death
If a mob's head is amputated, it does not die instantly. Instead, it enters a "headless" state where it will continue to wander or attempt to attack for a brief period (typically 3 seconds) before collapsing and dying permanently. This behavior can be toggled in the configuration file.
Physical Gibs
Severed limbs, known as "gibs," are treated as physical entities in the world. In older versions (Pre-1.6), these gibs could be punched or pushed around for entertainment. In modern versions like 1.12.2, they remain as temporary physical objects that eventually despawn to save on performance.
Supported Mobs
Mob Amputation specifically targets undead, humanoid mobs. While the original mod focused on three core types, later versions (1.10.2 and 1.12.2) expanded support to their variants.
Zombies & Variants
- Affected Mobs: Zombie, Husk, Drowned, Zombie Villager.
- Effects: These mobs feature red blood particles when limbs are removed. Removing arms reduces their visual threat, while removing the head triggers the delayed death timer.
Skeletons & Variants
- Affected Mobs: Skeleton, Stray, Wither Skeleton.
- Behavior Change: Skeletons have a unique mechanical change. If a Skeleton's bow arm is amputated, it can no longer fire arrows. Instead, its AI will switch to a melee-based attack pattern, charging at the player much like a Zombie.
- Note: Skeletons do not produce blood particles, only bone fragments.
Zombie Pigmen
- Affected Mobs: Zombie Pigman (Zombified Piglin in newer versions).
- Effects: Similar to Zombies, they produce blood particles. Removing their sword arm does not currently reduce their attack power but provides a significant visual indicator of damage.
