Deltapack

Deltapack is THE deltarune datapack that you have been searching for!

Whilst currently small it features a decent amount of content to kickstart your deltarune journey.

The Knife: Craft a knife then stab the ground to open a dark fountain, will convert nearby items into a darkner.

Snowgrave: Well that took a weird route, craft snowgrave and use the spell to freeze all nearby entities to death....

The Roaring Knight: The first (and currently only) boss! A difficult bullet hell styled fight where they attack first, then you get a chance to attack, mimicing the turn based combat of the original game.

The Shadow Mantle: Greatly reduces damage from firework and magic attacks, which happen to be the exact kind of attacks The Knight uses.

The Shadow Crystal: Drops from the Roaring Knight, consume it to gain their abilities!
