SlashExpansion is an add-on mod for SlashBlade: Resharped, adding 12 brand-new Special Attacks (SAs) and 12 brand-new Special Effects (SEs).

The mod adds no new blades — it focuses purely on enriching the skill system. Every SA scales off the blade you are currently holding, so damage grows with your gear instead of falling off late game. Each SA also plays a multi-stage timeline animation (charge → slash → impact → aftermath) rather than a single particle burst.

Everything is configurable: damage numbers, which chests drop which SA, and the crafting recipe of every SE.

📦 Supported versions

Immovable King	Immune to all damage for 3s while rooted, then deals 200% damage and knockback in a 10-block radius	200%	Bastion Treasure (8%)

Damage Calculation

All SAs share the same base damage formula:

Base Damage = max(10.0, Blade Base Damage + Refine×0.5 + Power Enchantment Level×2.0 + Player's Attack)

The base is then multiplied by each SA’s damage multiplier, keeping skills relevant as your gear grows. The lower bound, the Refine and Power bonuses, and every SA multiplier are configurable.

Thor’s Wrath lightning is visual only by default (visualOnly = true) — it does not create vanilla lightning damage or fire.

Rift Slash resolves each of its 8 blades at 180%, so a full hit is 8 × 180%. Tune damageMultiplier or bladeCount if that is too strong for your pack.

🎬 Visual effects

Each SA is a staged performance rather than an instant particle burst:

Custom particles — two procedurally drawn textures (glow soft halo, rune mandala circle) rendered with additive blending, so overlapping light builds into real glow.
Server-side timeline — every effect is scheduled tick by tick: summoning circles, converging light, falling blades, ground shockwaves, afterimages, jagged lightning, and so on.
Screen presentation — impact flash, edge vignette and camera shake are sent to every player within range.

Performance-minded packs can turn the whole system down with [vfx] (particleScale, maxConcurrentEffects, particleBudgetPerTick) or off entirely — damage and hit detection are never affected.

🎯 Survival Mode Acquisition

SAs: structure chests

Chests may contain a Blade Core (耀魂宝珠) carrying the corresponding SA:

Structure	Available SAs	Chance
Ancient City	Wan Jian Gui Zong, Senbonzakura, Frost Domain, Zhan Tian Ba Jian Shu, Jian Dang Ba Huang, Geng Jin Jian Jue, Qi Sha Jian Jie	10% / 20% / 15% / 10% / 10% / 8% / 5%
End Ship / End City	Rift Slash, Zhan Tian Ba Jian Shu, Jian Dang Ba Huang	25% / 12% / 12%
Bastion Remnant (Treasure)	Inferno, Geng Jin Jian Jue, Thor’s Wrath, Immovable King	15% / 10% / 12% / 8%
Nether Fortress	Wan Jian Gui Zong, Qi Sha Jian Jie, Blood Moon Slash	8% / 6% / 10%

SEs: crafting

All 12 SEs are crafted — check JEI or the recipe book. Recipes, including shapeless variants and the result item, are fully configurable.

Dragon Soul Resonance has only 9 crafting slots, so it uses 1 Dragon Egg + 7 Dragon’s Breath + 1 proud soul crystal.

How to Apply

Obtain a Blade Core with the desired SA, or a proud soul crystal with the desired SE.
Place the Core / crystal and any SlashBlade onto a Blade Stand (刀挂台).
Left-click to transfer the SA/SE to the blade.
Hold the blade and right-click and hold to unleash the SA. SEs are passive while the blade is held.

⚙️ Configuration

Everything lives in config/slashexpansion-common.toml (generated on first launch).

Section	Contents
`[damage]`	Base damage formula: lower bound, Refine bonus, Power bonus
`[sa.<skill>]`	Per-SA multiplier, search radius, blade count, effect radius, duration, effect levels
`[entities.giant_slash]`	Travel distance, speed and hit detection of the giant slashes
`[se.<effect>]`	Per-SE multipliers, levels, intervals
`[loot]`	Which structure chests drop which SA, and how often
`[recipe]`	Crafting recipe of every SE
`[vfx]`	Effect toggle, particle scale, concurrent limit, screen flash and camera shake

[vfx] is hot-reloaded; [loot] and [recipe] apply on /reload.

🛠️ Commands

/slashexpansion vfx <name>     # play an SA's full animation
/slashexpansion vfx list       # list every available name
/slashexpansion vfx ping       # diagnostic: emit custom particles + screen flash

Requires permission level 2. Handy for tuning, recording, or just watching the animations.

Test commands (Creative Mode, 1.20.1 / Forge)

/give @p slashblade:slashblade{SpecialAttackType:"slashexpansion:wan_jian_gui_zong"}
/give @p slashblade:proudsoul_crystal{SpecialEffectType:"slashexpansion:wind_god_power"}

Replace the id with any SA / SE from the tables above. On 1.21.1 / NeoForge, item data uses components, so use the crafting and loot paths instead — or preview any animation with /slashexpansion vfx <name>.
