SlashExpansion

SlashExpansion is an add-on mod for SlashBlade: Resharped on Minecraft 1.20.1, introducing 9 brand-new Special Attacks (SAs) to the game.

The mod adds no new blades — it focuses purely on enriching the skill system. All SA damage is dynamically calculated based on the blade you're currently holding, scaling with your gear and stats as you progress.

✨ New Special Attacks

SA Name	Effect	Damage Multiplier	Acquisition
Wan Jian Gui Zong	Summons 10–256 phantom blades from the sky; count scales with your xp level	80%	Ancient City (10%), Nether Fortress (8%)
Senbonzakura	Cherry blossom blade ring; 4–6 blades per target, piercing, with petal particles	120%	Ancient City (20%)
Rift Slash	Dash forward + 8-direction projectile wave	180%	End Ship/City (25%)
Frost Domain	Freezes enemies in a 20-block radius, applies Slowness X, Weakness II, and Mining Fatigue IV	80%	Ancient City (15%)
Inferno	Ground-shattering flame eruption + 8 seconds of burning; +50% damage to Nether mobs	100% + burn	Bastion Treasure (15%)
Zhan Tian Ba Jian Shu	Massive vertical energy slash, travels 64 blocks, ignores obstacles	150%	Ancient City (10%), End City (12%)
Jian Dang Ba Huang	Massive horizontal energy slash, travels 64 blocks, ignores obstacles	150%	Ancient City (10%), End City (12%)
Geng Jin Jian Jue	1–100 golden phantom blades (count tied to your Refine level), ignores armor	160%	Ancient City (8%), Bastion Treasure (10%)
Qi Sha Jian Jie	Domain deals 7 sequential hits, cycling through 7 damage types; range scales with your KillCount	100% × 7	Ancient City (5%), Nether Fortress (6%)

Damage Calculation

All SAs share the same base damage formula:

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

This base is then multiplied by each SA's damage multiplier, ensuring that skills stay relevant alongside your gear progression.

🎯 Survival Mode Acquisition

You can find special Blade Cores (耀魂宝珠) with embedded SAs in chests from the following structures:

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	15% / 10%
Nether Fortress	Wan Jian Gui Zong, Qi Sha Jian Jie	8% / 6%

How to Apply

Obtain a Blade Core with the desired SA.
Place the Core and any SlashBlade onto a Blade Stand (刀挂台).
Left-click to transfer the SA to the blade.
Hold the blade, then right-click and hold to unleash the skill.
