About this Mod

Overview

Tired of the same old "click-and-slash" Minecraft combat? Do you wish that fighting a monster felt less like a chore and more like an epic, strategic hunt?

                                                Welcome to Monster Expansion.

This mod is a ground-up recreation of the skill-based combat from games like Monster Hunter, built with zero dependencies on other mods. We haven't just added new mobs, we've added a whole new, dynamic way to fight them.

The Hitzone & Part-Break System

Gone are the days of mindlessly hitting a giant, invisible health bar.

Combat Mechanics

     Target Specific Parts: Monsters have different body parts with seperate health pools. These parts also have a damage type weakness. For example BLUNT is usually preferred to break a monster's head, while SLASHING deals more damage to its tail.

      Break & Sever Parts: Focus your attacks on a single part to break it, or use a slashing weapon to completely sever a monster's tail! These actions reward unique crafting drops.

      Elemental Weaknesses: Each individual part has its own unique set of elemental weaknesses. We've just introduced our first element, Ice, with many more planned for the future! A monster's head might be immune to Ice, but its wings might take massive damage from it. Monster armor also inherit the resistances/weaknesses for elements from the monster it was made from.

Your Skill is What Matters

Monster Expansion rewards precision, positioning, and movement. You can't just stand still and trade blows.

Active Dodging, Not Tanking: Monster attacks are specific and telegraphed, requiring good movement to dodge. Most heavy attacks will punch right through a vanilla shield or temporarily disable it. Eating too many attacks repeatedly will stun you, and some monsters have a chance to inflict unique status effects. Its advised to not face tank the monsters.

Dynamic Gameplay: Breaking a monster has real consequences. Sever a monster's tail, and its tail-swipe attack will have less reach because the parts that deal the damage are literally gone.
