Development
This mod is in an incomplete state and may contain bugs, incomplete content or inconsistencies. Feedback is welcome and appreciated!
Welcome to Catalyst! This mod aims to create a cleaner and more content-filled Hytale experience. Currently, the mod simply adds back items that didn't make it into the final cut of EA and adjusts them, but in the future, will contain custom items, damage types and more!
Current Features:
- Two new bosses, found in the Henge and Hedera portals, dropping Onyxium and Mithril respectively
- Onyxium and Mithril gear, with Onyxium gear dealing a new Void damage type (storm leather found in Windrider Valley for now)
- A WIP magic overhaul, adding mana to weapons, elemental attacks and mage builds
- Wraiths, Praetorians, and Spawn can rarely drop their weapons
- Brass and Steel ingots and gear
- 1 Handed Axes, Clubs, Staffs, Guns and Longswords
- A Loom to craft leather and cloth armor
- Other miscellaneous tweaks
Furnace Recipes:
Steel: 5x Charcoal, 1x Iron Bar
Bronze: 1x Charcoal, 1x Copper Ore
