This mod adds multiple items from DELTARUNE by Toby Fox, including:
The Shadow Crystal
Recipe:
Spoiler
This item finally puts another use to those stupid Echo Shards you find in the ancient cities. This item, on its own, does nothing special, but you will need them to craft the next item:
The Pure Crystal
Recipe:
Spoiler
This item acts as a strong weapon, just like the "Black Shard" in DELTARUNE (that item is not in this mod). You can only use it 32 times though, so you better save it to craft the next item:
The Black Knife
Recipe:
Spoiler
This is an extremely OP weapon, able to deal 55 attack damage, and has very high durability. It can be repaired using more Shadow Crystals.
