I have implemented Genshin Impact-style elemental reaction mechanics in the Iron's Spells 'n Spellbooks mod.

The mod currently integrates with: T.O Magic 'n Extras, Alshanex's Familiars, GTBC's Geomancy Plus, Mechanicraft, Cataclysm: Spellbooks, Apprentice's Codex, and Wind's Spellbooks.

Regarding reaction design: the 9 base schools + T.O Magic "are designed by first conceptualizing each school's core identity, then combining them in pairs." Some interactions (e.g., Burning) are inspired by the source material with slight twists.

Other add-ons like Familiars, Wind's Spellbooks, and Geomancy Plus draw inspiration from Anemo, Geo, etc. — meaning they can only trigger a single type of elemental reaction, with some personal interpretation added.

【General Design Concepts】
- Fire: damage amplification
- Ice: speed reduction
- Lightning: area damage
- Ender: attribute reduction
- Holy: healing / undead specialization
- Blood: grievous wounds / self-healing
- Nature: debuffs
- Evocation: temporary casting stat boost
- Eldritch: temporary spell power boost
- Familiars (Alshanex): self & minion buffs
- Geomancy (GTBC): shields
- Abyssal (Cataclysm: Spellbooks): damage over time (Tidal Claw)
- Mechanicraft: initially planned as "homing lock-on", but that was too abstract to integrate, so changed to vulnerability & damage reduction.
- Wind (Wind's Spellbooks): the classic "Swirl" (elemental spread).

我在Iron's Spells 'n Spellbooks模组实现了原神的元素反应机制。模组目前已与源流（T.O Magic 'n Extras）律灵（Alshanex's Familiars）岩土（GTBC's Geomancy Plus）械术、深渊（Cataclysm: Spellbooks）奥术（Apprentice's Codex）疾风（Wind's Spellbooks）进行了联动关于反应设计：基础9派系+源流是“在构思出流派基础特色后，两两结合做出”部分致敬原著略特殊，比如燃烧然后律灵、疾风、岩土等模组则是参考了风、岩等元素，即：只能触发单一类型元素反应；然后加上一些自己的理解【大致设计思路】火：伤害增幅、冰：速度降低、雷：范围伤害、末影：属性削减神圣：回血/亡灵特攻、血：重伤/回血、自然：Debuff 唤魔：临时施法属性提升、邪术：临时法强提升律灵：自身及随从增益、岩土：护盾、深渊：持续伤害(潮汐利爪) 械术一开始打算设计成锁头，但这玩意联动性太抽象，所以改成了易伤与减伤，疾风则是最经典的扩散
