There is going to be a lot of detail here, but I don't want it to be overwhelming so I'll keep it short. None of this is set in stone, but generally the direction it's headed in.
Crafting is when you take a recipe of items, put them into the Cube, and Transmute them into something else.
There are known recipes and will be unknown recipes. Rune Word NFTs are craftable from known recipes.
It can be revealed that TIR and EL can be put into the Cube. Once placed, you can Transmute those runes into the very first Rune Word STEEL.
Crafting Rune Words will unlock the power of the runes, creating unique items with attributes that have random ranges.
Rolling / Minmaxing
Rune Word NFTs and unique NFTs have a list of attributes, with random ranges.
For example, Alice might roll +10% farm bonus when crafting STEEL, but Bob only crafted +5% farm bonus. Poor Bob.
Rune Words in Rune.Farm have farming related attributes.
Rune Words in the Arcane Sanctuary game will have RPG related attributes that look something like this:
Transmuting (also known as slamming)
After you are happy with your roll in the Crafting Cube you might want to upgrade it even more by crafting it with a Worldstone Shard.
By putting the Worldstone Shard and the cubed item in the Cube once again and transmuting them, you are sending your item through time and space, where it comes back to you in a different form.
This new item could be extremely stronger, or extremely weaker and even could be fractured.
Fractured items cannot be cubed again.
The Worldstone Shard is very special as it has the ability to transmute items.
This can improve the attributes, sometimes add new attributes, and even make that item much weaker.
To be able to claim your Worldstone Shard all you need is to craft and equip the Rune Word LOREKEEPER (see rune.farm/runewords for known Rune Words) and 'Claim Shard' in the Farms.
Worldstone Shards are limited to 1 per week.
