How Upgrades Work

Upgrades are crafted as items first, usually from a Blank Dark Steel Upgrade plus a themed ingredient.

After crafting an upgrade, apply it to compatible equipment in the Smithing Table.

Most upgrades also require XP levels to activate. The XP cost is shown on the upgrade tooltip and in JEI recipe information.

Tiered upgrades must be installed in order. For example:

• Empowered II requires Empowered I
• Speed II requires Speed I
• Inventory II requires Inventory I
• Elytra requires Glider

Main Difference From Legacy Ender IO

The original 1.12 system used the Dark Steel Upgrade GUI and Dark Anvils to insert, remove, and store upgrades.

This 1.20.1 version simplifies that system:

• Upgrades are installed through the Smithing Table.
• Upgrade recipes are visible in JEI.
• The old multi-slot Dark Steel Upgrade GUI is not used.
• Pocket Anvil is kept as a portable infinite anvil upgrade.
• Micro Anvil and Mini Anvil were removed as installable upgrades.
• Glider and Elytra are treated as a progression line: Glider -> Elytra.
• Jump has two tiers instead of three:
  • Jump I: higher jump and fall damage protection
  • Jump II: higher jump, fall damage protection, and two extra air jumps

Upgrade List

Empowered

Compatible with most Dark Steel equipment and Ender/Stellar equipment.

Stores FE and lets the item use energy instead of durability or damage. Armor also absorbs part of incoming damage while powered.

• Empowered I: 100,000 FE, 50% damage absorption
• Empowered II: 150,000 FE, 60% damage absorption
• Empowered III: 250,000 FE, 70% damage absorption
• Empowered IV: 1,000,000 FE, 85% damage absorption
• Empowered V: available for The Ender and Ender/Stellar equipment

Powered tools gain the official Ender IO mining bonus:

• +2.0 mining efficiency while the item has Empowered and stored FE

This bonus does not scale by Empowered level.

The Ender Empowered Bonuses

The mod uses Ender IO's existing The Ender sword instead of adding a duplicate sword.

When powered, The Ender-style swords gain:

• Empowered I: +1 attack damage, +0.40 attack speed
• Empowered II: +2 attack damage, +0.45 attack speed
• Empowered III: +3 attack damage, +0.50 attack speed
• Empowered IV: +4 attack damage, +0.55 attack speed
