Limbus Core

Description

A core library and visual engine designed to support my current and future Limbus Company character mods in StS 2. 
Currently required for The Index Nursefather Yi Sang mod.

Main features

1. Sanity System (SP): A fully functional SP resource (ranging from -45 to 45) with unique mechanics and risk/reward thresholds.
2. Status Library: Shared logic for Limbus specific mechanics: Poise, Sinking, Bleed, Burn, and more (supporting both Potency and Count).
3. Damage Types: Introduces Slash, Pierce, and Blunt damage logic.
4. Cinematic Visuals:  - Limbus-style letterboxing with scrolling ink effects. - Automatic UI suppression during cinematic sequences. - Extended combat environments to allow for high-mobility animations. - All options are toggleable.

Sanity System (SP):

Full Details:
- Basics: SP starts at 0 each combat. It is used as a resource for E.G.O cards.
- Scaling: Gain SP equal to 100% of damage dealt and a flat 5 SP per kill. Lose SP equal to 200% of damage received.
- Detriments: Between -1 and -40 SP, you have a chance to deal reduced damage.

• Failure Chance: -(SP*3)% (e.g., -20 SP = 60% chance).
• Damage Reduction: Current -(SP*1.5)% (e.g., -30 SP = 45% reduction).

- Panic: At -30 SP, the player is inflicted with a unique Panic debuff.
- Turn Skip: Between -35 and -45 SP, there is a chance to completely skip your turn (50% at -35 SP, 100% at -45 SP). After a skip, SP resets to 0.
