Mods Upgrader items 1.0.0

Upgrader adds a single item: the Upgrader. Right-click it to open the wheel.

Drop an item into the left slot, pick what you want out of the list on the right, and the mod works out your odds. Hit the button and a marker runs around the wheel — if it stops inside the gold zone, your item becomes the one you asked for. If it doesn't, the item is gone.
​

Odds you can reason about​

• Modded items are priced automatically. If it has a recipe, it has a value. No compat patches needed.
• Damaged tools are worth less, in proportion to the durability left.
• The success chance is 0.9 × (your item's value ÷ target's value), capped between 0.1% and 90% — so a downgrade is never a guaranteed win, and a wild gamble is never truly impossible.

Details​

• Crafted from 4 gold ingots, 4 diamonds and an anvil.
• The roll happens on the server, so the client can't lie about the outcome. Safe on multiplayer.
