This is an SKSE plugin.

I just learned how to make an SKSE plugin recently, so it currently only a few functions as of right now.
But feel free to make requests! I am probably, for the time being, more readily available than the SKSE team. Although, probably also less experienced.

What is this and why do I need it for SkyTweak?
This is an extension to SKSE's functionality. So think of it as just more of SKSE.
It won't affect your game directly, it just gives other mods more options and tools.

SkyTweak uses this to optimize string parsing. IE it makes the MCM menu run faster. And it lets SkyTweak edit torch properties.
Grimy Utilities uses this to implement the enchantment cleanser
Grimy's Skill Expansion uses this to implement spellcrafting and as an enchantment cleanser.

I don't have it prepackaged with my mods because Mod Organizer gets confused and sorts overwrites based on load order, instead of "most recently updated", which has been causing a few of my users issues. It's more reliable to have it stored on a separate mod page for now. But I will strongly consider prepackaging it in the future, after I stop updating my plugin so frequently.

Int Function MergeSpells(Spell outputSpell, Spell[] inputSpells, Float[] magMults, Float[] durMults, Float[] costMults, Float timeMult) Global Native
;This is a custom function I built for personal use, and is designed to be optimized to my own spell crafting needs
;The spells in the input spells section are merged into the output Spell
;magMult, durMult, and costmults apply multipliers on the magnitude, duration, and cost of their corresponding spell EffectShader
;If you have fewer input spell effects than in the outputSpell, then the excess magic effects in output spell will be left
;timeMult is a multiplier for the cast time of the spell. it applies a corresponding multiplier to magnitude and cost, but only for effects that are deemed to not be "buff-based" magic effects.
;Returns -1 error if cast types of the input spells did not match DEPRECATED
;Returns -2 error if delivery types of the input spells did not match DEPRECATED
;Returns -3 if there are more magic effects in the input spells combined than in the output spell.
;Returns -4 if the input arrays are not of equal size.
;Returns 1 if a spell was made, BUT the spell has no school.
