ForgeNeoForgeClient and serverAll rights reserved1.20.1 – 1.21.1

What it does

Each material brings a sword line with an ability that triggers on hits. Ignitium weapons apply the Blazing Brand effect to the target with a 75% chance for six seconds. Repeated hits raise the effect's amplifier up to a maximum of 4, and each step lowers the target's armor and armor toughness in proportion to that amplifier. Attackers wielding Ignitium weapons recover a small amount of health through an Ignis lifesteal ability, which depends on attack speed, the Blazing Brand amplifier and the lifestealMultiplier config. Cursium weapons apply Accursed Rage to the user and add bonus damage based on its amplifier, and the ability mimics the rage meter of Maledictus.

Ancient Metal and Black Steel weapons have extra abilities of their own. Ignitium, Cursium and Witherite weapons are fireproof and unbreakable, and they use custom sounds and particles. The mod requires L_Ender's Cataclysm and Simply Swords, and Better Combat is optional. The mod is licensed All rights reserved and is not open source. Its builds cover 1.20.1 and 1.21.1 on both Forge and NeoForge.

Key features

  1. Ignitium blaze weapons

    Ignitium swords apply Blazing Brand on a 75% hit chance, lowering the target's armor with each stack.

  2. Cursium rage weapons

    Cursium swords grant Accursed Rage to the wielder, adding damage that scales with the effect's amplifier.

  3. Witherite weapons

    Witherite swords inflict Wither II and set targets on fire, and heal the user with Regeneration II when health is low.

  4. Mecha Pulse charge

    Pulse Charge builds on hits and releases a shockwave at maximum amplifier that stuns the target for 10 seconds.

How it compares

Full comparison

Cataclysm Tools is client and server and also works alongside the boss mods, but it is a tools mod with its own tool set and is not open source. Cataclysm Weaponery is client-side only and covers versions 1.16.5 – 1.21.5, so it can run without server installation. Goety Cataclysm is client and server and targets versions 1.20 – 1.21.1, adding Cataclysm content to Goety.
