Alchemist's Arsenal

by Nitespring

Alchemist's Arsenal adds alchemical weapons, utilities and equipment with a steampunk look, built to give several vanilla resources more uses.

What it does

The mod groups its content around alchemy and steampunk aesthetics. Potions can be crafted into unstable concoctions that grant special effects, and attacks with certain weapons set enemies on fire or inflict poison. A substitute for bone meal grows plants across a 3x3 area, and an enhanced version covers 5x5 and works faster.

Its weapons include a hybrid of crossbow and warscythe. It has the reach of a melee weapon, extending 2.5 blocks farther than a standard strike, and a charged shot fires three stronger projectiles at once or sends arrows in quick succession from inventory without reloading. The charge needs a manual recharge after 24 uses. A late-game elytra upgrade adds boosted flight with a key, drawing on fuel kept in the inventory. Fuel is coal or charcoal by default, and a datapack can change it through a fuel item tag. Wing textures are set on the item through a data component, so different players or teams can show different wing styles.

Late-game armour in netherite gives strong defence, toughness and knockback resistance, at the cost of a noticeable drop in movement speed, low enchantability and more fall damage. The armour can nullify the health gain, so a player wearing it can be killed at normal heights, and can survive otherwise. The mod needs NeoForge and runs on client and server, so the server and every player need it. Files are published for 1.21 and 1.21.1, with 1.1.0.5 for 1.21.1 as the latest release. The mod is licensed as All rights reserved, and source code is publicly available.
