Sephiria Fantasy

Sephiria Fantasy is an unofficial fan mod that brings the weapon system of SEPHIRIA into Minecraft. This project makes heavy use of AI-generated code — shared for learning and personal use only, and commercial use is not allowed.

Alpha stage: there is a decent amount of content, but most of it has not been playtested thoroughly yet — numbers and feel are still being tuned.

Contents

Six base weapons

Blade / Steel Greatsword / Dagger / Default Sword and Shield / Quarterstaff / Colossal Crossbow — each with its own normal-attack feel and weapon skills (sweeping, whirlwind, dash, area lunge, …). The blade-type weapons are animated with GeckoLib.

Eleven combo sets and 66 artifacts

Sturdy / Wind Song / Precision / Shadow / Negotiation / Element / Magitech / Dark Cloud / Sun Sword / Embers / Glacier.

Equipping artifacts of the same set in the Sephiria Backpack raises that combo's tier, and higher tiers give stronger effects. Hover a combo icon to see its full tier table. Artifacts come in five rarities (Common / Advanced / Rare / Legendary / Bond), and a 【Unique】 artifact only counts once no matter how many copies you carry.

Debuffs and artifact skills

• Shock (Magitech), Burn (Embers) and Frostbite / Freeze (Glacier): periodic damage that scales with stacks, plus a freeze that locks a mob completely in place (no AI, no knockback, animation held on the spot) and turns it ice blue; affected mobs show a stack label under their feet. Debuff damage and true damage can crit as well.
• Artifact skills: 6 skill slots with rebindable keys — Encouragement Banner, Haste, Keen Eye, Thunder Verdict.

Attributes and progression

Physical Power, Fire / Ice / Lightning element strength, crit chance and crit damage, dodge, defense-ignoring (true) damage, movement speed, mana, Leaves (currency), and more. The Attributes page is two columns; hover an entry to see its formula.

Shop and chests

The shop's shelves are rerolled with Dice: put dice into the shop's dice slot and press the "Refresh" button to spend one and get a fresh set of goods (placing dice alone does not reroll anything, so you cannot waste one by accident). Your Negotiation stat lowers buy prices. Dice come from naturally generated loot chests (~10%) and from harvesting fully grown carrots (~1%); the shop does not buy them back. Chests come in three kinds: Artifact / Slate / Upgrade.

Effects

Red Snake Eye meteors play a four-stage show (appear / fall / impact / vanish); plus Sun Sword slash marks (a straight, glowing cut in one of three random directions), the Thunder Verdict beam, Dark Cloud lightning, custom particles and procedurally generated sound effects.

Requirements

Installation

1. Install Fabric Loader and both dependencies above;
2. Drop sephiria-fantasy-<version>.jar into mods/;
3. Launch the game — it works in singleplayer right away; for a server, install the same jar on the server side too.

Known issues / not done yet

• Most content has not been playtested thoroughly; numbers and feel are still being tuned;
• Backpack expansion, slate upgrades, forging and the companion system are not implemented yet;
• Some texts and icons will still change.
