There is currently an issue with Hytale's Update 3 where the server will fail to load with the mod installed. The solution to this is just checking the "skip mod validation" in the world settings. I'm working on fixing this properly though. 

Video Showcase:

Crelly

At the moment, a spawn egg for the NPC is crafted at the HyRise workbench, but in the future, she will spawn in the wild where players will be able to encounter her.

Crelly will offer trades for plant and nature based items, most commonly involving moss or poison. Like all the merchants, Crelly's inventory will grow over updates, with custom mold items from HyRise, and swamp based items from the vanilla game. She will also sell you her chair.

Weapons:

          Moldy Longsword

Crafted wtih 14 Iron, 10 Thorium, 3 Medium Leather, and 25 mold. The mold is so potent that it causes the sword to glow a dull green. The sword has a spinning slash basic attack, and a horizontal dash charged attack.

Moldy Shurikens             

Crafted wtih 1 Mold, and 5 copper, Moldy Shuriken are cheap, consumable, ranged weapons.

Items:

Mold:

Mold is a crafting item that is created with 5 fruit and 2 flour. Mold can both be sold to Crelly, as well as used to craft Mold based items.

Cowbell Necklace:

The Cowbell Collar is a cosmetic item primarily used for crafting Crelly spawn eggs. It may have other uses in future updates.

Like the rest of HyRise, this mod is still under development. The actual barters right now are placeholders until I have a more fleshed out collection of custom items.
