Your Gem Stash
How many of each gem do you currently own, per color and size? (not counting equipped gems)
Equipped Gems
Your 4 currently equipped gems. They're melt-able / usable for transmutation, just like stash gems.
Resources On Hand
Aether and Godstones you already own, by rank. The calculator uses these before buying more.

How this calculator works & assumptions
- Upgrading requires 3 gems of the exact same size and the exact same color, plus 1 Aether whose rank matches the source size (3× size 1 + Aether rank 1 → 1× size 2; 3× size 2 + rank 2 → size 3; 3× size 3 + rank 3 → size 4). You cannot mix colors or sizes, and the resulting gem keeps that same color.
- If a gem's color doesn't match your target, a recolor (1 Aether rank 3) is paid immediately when the gem is picked up.
- Recoloring is a flat cost (1 Aether rank 3) regardless of gem size.
- Creating fresh size-1 gems from a batch recipe (e.g. rank 3 → 3 gems) produces bonus gems when you only need one — those extras are kept in your pool for reuse on other targets, they are never wasted.
- The solver always prefers gems and resources you already own over buying new Aether/Godstone with Mark of Fellowship.
- Exact color+size matches already sitting in your stash or equipped slots are used first, for free, before any crafting is considered.
- This is a fan-made tool based on the rules as described; it is not affiliated with the developers of Fellowship.
