Monster Expansion
by Saksolm
Monster Expansion changes how players fight large monsters by splitting each one into body parts with their own health, damage weaknesses and elemental weaknesses, for Forge on 1.20.1 – 1.20.6.
What it does
Each monster has several body parts that carry separate health pools. A part takes more damage from certain damage types, so blunt attacks are the usual choice for breaking a head, while slashing attacks deal more damage to a tail. Attacking one part repeatedly breaks it, and a slashing weapon can sever a tail outright. Breaking or severing a part yields crafting drops that are not available from other sources.
Combat depends on positioning and movement. Monster attacks are telegraphed and specific, so players dodge them rather than absorbing them. Heavy attacks can punch through a vanilla shield or disable it for a time, and taking too many hits in a row stuns the player. Some monsters can also inflict status effects. A severed part removes the damage it dealt, so a monster's tail swipe loses reach once the tail is gone. Armor made from a monster inherits that monster's elemental resistances and weaknesses.
Installation covers the server and each player's game. Files are published for Forge only, across six game versions: 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5 and 1.20.6. The mod has no dependencies on other mods, and the code is covered by All rights reserved, so it is not open source.
Key features
Targetable body parts
Monsters have separate body parts, each with its own health pool that must be broken before the part is lost.
Damage type weaknesses
Each part reacts differently to blunt, slashing and other damage types, which shapes the choice of weapon.
Part severing
A slashing weapon can sever a monster's tail, and the severed part no longer contributes its damage.
Elemental weaknesses per part
Each part has its own set of elemental weaknesses, with Ice as the first element added so far.
Telegraphed monster attacks
Attacks show their timing and direction, so dodging is an active choice and standing still costs health.
