As someone who tried ItemAdders and Nexo, this plugin is so amazing.
I've already created custom potions, armor, weapons, blocks and furniture. You can add so many unique items to the game and customize them as you please!
Pros:
1: custom abilities to items, furniture, and blocks.
2: no coding needed
3: when you get the hang of it you'll really love it. Give it time.
4: pre-recipes already made which helps.
5: you don't see the hitboxes in furniture's like you do in itemsadder.
cons:
1: To get started takes a little bit to get used to but the wiki does a really good job on teaching you step by step. If you don't give it time you won't see the potential of this plugin.
Everyone should came for trying this plugin, open-source, community-driven, and what's more? It's not only a simple alternative for ItemAdders or Nexo, it's a better replacement for them!
So just buy the full version if you can!
We bought the paid version on the release, I don't regret anything! A very good plugin for adding user-generated content, as well as other resources by this author!
