About this project
What does Dungeon Difficulty add?

☠️ Location based difficulty
Location based difficulty, based on either one of these:
- dimension
- biome (id/regex/tag)
- structure (id/regex/tag)
Various difficulty types, defaults include:
- Adventure (increasing mob attributes: max HP, damage, armor)
- Dungeon (same as Adventure + increasing power of looted items)
- Heroic (same as Dungeon, with different name to indicate boss fight)





Some example mobs: 
🗡️ Loot scaling
Matching the location specific difficulty, items are scaled up:
- Indicated as "Power Level" on the item tooltips
- Predefined attributes (such as attack damage, max health) get added or increased
- Works on defined items and attributes (vanilla and modded) - Reworked item rarity (enchanted items are Uncommon, scaled up items are Uncommon, enchanted + scaled up items are Rare)
This mechanic motivates players for exploration and dungeoneering instead of base camping and crafting.
👨👩👧👦 Per player difficulty
Additional players in a multiplayer game, silently increase the difficulty.
🔧 Fully configurable
This mod has a very flexible configuration, that uses id/regex/tag based matching, allowing
- any combination of dimension, biome and structure to define difficulty
- custom difficulty types to be added
- any attributes to be scaled on looted items (vanilla and mod attributes)
