A new library/API mod for all of my Iron's Spellbooks Addons!

This mod does not do ANYTHING on it's own!!

This mod is mainly created for Iron's Spellbooks add-on developers and myself included in mind... Since I have soo many ISS addons it's annoying to copy-paste every necessary things from one place to another whenever I start working on a new addon. Thus.. this library is created!

What this Library/API mod adds:

New Attributes like Spell Crit rate/DMG, Spell Projectile DMG, Spell Damage
Many pre-made patterned particle managers
AdvancedRandomImbuingCurio class to create curios that on right-click, imbues itself with specified random spells
Easy way to create flexible trades with AdvancedTrades class
Comfortable armor imbuement options with customizable slots and pre-imbued spells with AbstractImbueableArmorItem class
Geckolib Geo armor items, Geo magic sword items with GeoArmorItem & GeoMagicSwordItem classes
MultiAttributeCurio class that support multiple attributes
AdvancedSpell class for playing random animations and sounds on cast start-finish from a list, with a boolean to choose either play them on a order or not
CurioUtils class for easily checking wearing curio on a player
SummonCheckHelper class for checking summons in a radius with owner (I mainly use it for summon limit system on T.O Tweaks mod)

Why your project is Closed Source and How can we get access to it?

In the past, I had some unfortunate experiences with my college projects (personal matters) that left me with trust issues. Let’s just say I’ve developed a sort of trauma, and it’s hard for me to trust people easily. Since I’m fairly new to this community, I feel the need to be cautious. That’s why my projects are currently closed-source. However, if I stay in the modding scene long enough and build more trust, I might consider making them open-source in the future.

For now, if you’re a known modder or someone I personally know and you’d like access to my projects for personal use or to help me directly, feel free to reach out. You can contact me on Discord or CurseForge, and I’ll gladly provide collaboration access to my GitHub repositories.

Initial Post on Modrinth

here's actual changelogs for the file itself - continuing from last CF upload (1.5.0)

1.6.0

Update to latest ISS 3.16.2
Spell Crit Chance is now percentage based with 100% as the neutral baseline. 100% = no crits, 102% = 2% crit chance

New: SpellCritEvent

Pre — modify crit chance and crit damage before the roll, or force/prevent a crit outright via CritOverride.
Post — fires only on a landed crit; modify the final damage or hook on-crit effects.
Both phases expose the caster, target, damage source, and pre-crit damage etc
