What does Just-In BLACKSMITH add?

Use the weapon smithing table to imbue your weapon with various attributes from smithing stones, carefully crafting your ideal weapon step by step.

4 TYPES NEW WEAPONS & TOOLS

4 Weapons & Tools

Attacks accumulate a Stun value on the target. A higher Stun value increases the chance of stunning the target.

Just a spear! Hold right-click to enter a ready stance, continuously thrusting at forward targets.
Attack damage bonus scales with movement speed.

Sneak (Shift), adjust your viewing angle, and right-click to play the Vihuela. Playing its three strings will upgrade three of the Vihuela's attributes: Range, Power, and Area of Effect.
Each attribute can be upgraded up to three times, with a maximum of five upgrades in total.
The Vihuela can perform melee attacks or fire musical notes as a ranged attack. Different combinations of upgrades will yield unique combat effects.

Right-click to briefly block. A successful block activates the Sliding Slash stance, causing your next attack to dash through the target.
SPECIAL APPEARANCE
Special materials grant unique textures and models to crafted tools and weapons.

FORGING GUIDE
Materials can be crafted into various parts and upgrades. Each material features distinct properties, and some even come with exclusive affixes.


Check the Forging Guide for more details.

I've always loved the tool assembly system in Tinkers' Construct, which allows you to customize weapon stats and abilities. However, I found the smelting and casting processes to be a bit too tedious. That's why I created this mod—it lets you directly assemble your ideal tools using base materials without the extra hassle. Moving forward, I will continue adding material compatibility for other major mods.
