Grimoire of Gaia Spell Integration for Iron's Spellbooks

This mod expands Iron's Spellbooks with spells inspired by Grimoire of Gaia, allowing you to summon monster girls from GoG to fight by your side.

Unlike their non-summon versions, these summoned versions slightly adjusted AI and attack patterns for better combat performance and synergy with Iron's Spellbooks’ mechanics.

✨ Notes

• Highly Configurable in config/GoGSpellsConfig.toml.
• Their Summon Scrolls are craftable, just check them in JEI.
• You can also craft a necklace The Blessing of Gaia which adds bonus drop rate of certain loots when killing certain mobs, with which you will be able to craft those scrolls earlier.

Q: The summoned monsters feel like they could be improved—any plans for that?
A: Since these creatures are originally from Grimoire of Gaia, their AI and behavior are a bit on the simple side. They also don’t use Geckolib, so their animations and movement logic are limited by the base mod. I might tweak them further down the road, but for now, they stay close to their original design.

Enjoy commanding your Grimoire of Gaia monster girls with the power of Iron’s Spellbooks!
