Yone Dual Blades

A Forge 1.20.1 addon for SlashBlade: Resharped that brings a League-of-Legends-style dual-blade wielder into your world. Craft a pair of bewitched katanas — one wind-aspected, one fire-aspected — and dual-wield them to unlock swap combos, three SlashArts, and a custom passive.

Crafting

Combine a Wind-charge Blade + a Burning Blade + a Blaze Powder in a smithing table to obtain both Yone Blade (Blue) and Yone Blade (Red).

The Two Blades

Blade	Color	SlashArt	SEs	Base ATK
Yone Blade — Blue (Sealing Blade — Aoran)	Green	Wind Shadow (Z)	wind_guard / wind_slash / wind_purify	8
Yone Blade — Red (Breaking Blade — Chijin)	Red	Fire Slash (X)	fire_burn / fire_slash_se / fire_purge	8

Holding both at the same time is Dual-Wield mode. Plays a 6-hit swap combo on regular clicks, grants the dual-wield passive, and unlocks the ultimate.

SlashArts

Z — Wind Shadow (Blue Blade, single-wield)

• Dash forward along the look-vector (DashManager.dash_speed, default 1.5)
• Vertical green sword beam (color 0x33FF33, scaled 2.0×)
• Knock up enemies on the path; execute targets below 5% HP
• Magic damage = attack × WIND_SHADOW_DAMAGE_MULT (default 1.0); applies Slowness VII for 3 s
• Cooldown: 5 s (attack-speed-scaled, min 1 s)

X — Fire Slash (Red Blade, single-wield)

• 60° forward cone; one hit per target
• Physical damage = target.maxHealth × fire_slash_pct (default 7.5%)
• Magic damage = target.maxHealth × fire_slash_pct (default 7.5%)
• Applies Poison I (5 s) and fire ticks
• Self-shield: Absorption ≈ 5 + 20% max HP for 3 s
• Dual-Wield bonus: crit rate override → 150% (guaranteed crit + 50% overflow); crit damage × (1 − fire_slash_crit_reduction, default 0.9); every 1% overflow converts to 0.04 × attack as extra physical damage
• Cooldown: 5 s (attack-speed-scaled, min 1 s)

R — Yin-Yang Judgement (Dual-Wield ultimate)

• Dash 5 blocks; quad-direction sword beams; knock up targets along the path
• 5 ticks later: snap to the last hit target's back, deal 4 cross-beams
• Each beam: attack × YIN_YANG_DAMAGE_MULT (default 2.0) split 50 / 50 physical + magic
• Applies Poison I (6 s), Wither II (6 s), Weakness I (5 s), 30-tick Stun (1.5 s), extreme Levitation (1 s)
• Executes targets below 10% HP
• Cooldown: 10 s (fixed)

Dual-Wield Passive

While dual-wielding, every third attack deals bonus magic damage = attack × PASSIVE_DAMAGE_MULT (default 1.5). Stacks on top of normal hit damage and ignores armor — great against tanky bosses.

Special Effects (SEs)

Six SEs ship with the blades — buy them with XP levels in their slot:

SE	Effect
wind_guard	Removes fall damage; adds constant Speed I
wind_slash	+30 % damage against undead mobs
wind_purify	−15 % damage taken from demons (was +15 %; bug fixed)
fire_burn	Sets targets on fire for 3 s on hit
fire_slash_se	Extra burn duration vs. demons / piglins (6 s)
fire_purge	−40 % damage taken while in water

New Enchantments

Registered through EnchantmentRegistry:

• Swiftness — accelerates the dual-wield combo
• Ferocity — augments crit rate / damage (max level ferocity_lv_max, default 3)

Apply them at an enchanting table on either Yone blade.

In-Game Configuration

Cloth-Config integration lives under Mod Menu → Yone Dual Blades:

• SlashArt multipliers: fire_slash_pct, fire_slash_crit_reduction, fire_slash_overflow_per_pct, yin_yang_damage_mult, wind_shadow_damage_mult, passive_damage_mult
• Cooldowns for all three SlashArts
• Stun duration, dash speed, dual-wield passive mob blacklist, bewitched-recipe toggle

All changes persist to config/slashbladeyone-common.toml.
