Ice Formation - Cursed Fate Addon

The six abilities are Ice Shard, Frost Calm, Icy Grasp, Ice Slide, Maximum Output and Ice Age. Ice Shard launches a razor-sharp shard that slows enemies on impact, and its charge attack fires eight shards at once. Frost Calm summons nine large ice pillars over a chosen spot, and anything inside that area is frozen and takes damage. Icy Grasp seizes an enemy in front of the caster, locks it in place as frost consumes it, then launches it away.

Ice Slide glides across the battlefield at high speed and forms ice beneath the caster's feet, and its Flow Variant freezes the ground along the path so enemies that pass are slowed. Maximum Output channels a greater cursed energy technique that dramatically increases the size and devastation of certain attacks, while Ice Age releases a cataclysmic wave that encases nearby mobs in solid ice and deals heavy freezing damage. The addon is a Forge mod that runs on client and server, so the server and every player need it. It is published for 1.20.1 only, with the 6.0.0 file as the latest build, and is released under the MIT License, which means it is not open source.
