About this project
What does Iron Rune Forging add?
APPLY RUNES TO YOUR GEAR
Inspired by the enchanting system from Elder Scrolls Online, combine 3 runes to get a desired effect.

I really like Eso's enchanting system and I always wondered what would it look like if translated to other games. In this case, I'm using Iron'S Spells mod as a perfect base for such concept.
HOW DOES IT WORK?
Craft yourself a Runic Dagger and look out for Runestones out in the wild.

Each essence runestone has a preferred enviroment but any runestone has a chance to spawn at any location.
<---<oOo>--->

Essence Runes (Circle) represent Iron's schools of magics
Aspect Runes (Triangle) govern what the enchantment will do
Potency Runes (Rectangles) dictate the quality of the enchantment
Mix and match them together to create an enchantment that you want.
<---<oOo>--->
Craft a Rune Forge to begin enchanting your gear!
<---<oOo>--->
Your gear will get a sigil on it's item icon, to help you distinguish the enchanted gear.
*You can re-enchant the same gear*<---<oOo>--->
You can track how many runes you have and which ones you haven't discovered in the Rune Collection

Default hotkey is J but you can rebind it in the settings.

I didn't intend for it to be the better/easier alternitive to getting gear that fits your chosen school. It's meant to be a more in-between filler that helps you scale in the long run. I want the base Iron Spells progression to contiue to be relevant and feel like a milestone when you get your first armor set. This addition is here to pick you up when you feel like you have fallen behind. So please let me know if numbers need to be adjusted to meet that vision. I didn't really get to test it in big modpacks, so I'll be interested to see how it stands up to various modpack's balances.
Some numbers here:
ESSENCE RUNES
Fire, Ice, Lightning, Nature, Blood, Ender, Holy, Evocation, Magic
I decided not to do eldrich because it's not meant to be accessed early on.
