iom857's Masteries
by baldscreech
iom857's Masteries adds a skill tree to the Advancement screen, where players spend experience points on purchasable skills that change how the game plays.
What it does
The skill tree opens with the U key and is drawn with the vanilla Advancement GUI. Each skill is bought with experience points, and a purchased skill stays active for the rest of the save. Skills cover several areas: enchanting, ranged and melee combat, and animal husbandry.
Enchanting upgrades reduce the lapis cost of enchanting, with a chance that the lapis is refunded. Ranged and melee boosts raise bow damage and attack speed, and a set of hidden challenges adds extra effects such as piercing on bows and crossbows. Husbandry boosts make breeding quicker, with a 30% chance that a pair of animals produces two babies instead of one, and speed up baby growth.
The mod adds a buy-max upgrade that spends all available experience on a skill at once, and the optional Controlled Buying addon lets players scroll to choose how many levels to purchase. The Fabric build targets Minecraft 26.2 and is released under the MIT License, and the source code is public. Client and server both need the mod, so players and the server run it together.

How it compares
Vanilla-Skills runs on Fabric and NeoForge for 26.1.2 – 26.2, needs the server while the client may skip it, and is not open source. The Advanced Tool Mastery is a Fabric mod for 26.1.2 that runs on client and server, under All rights reserved. Ascension Mastery is open source under the MIT License and runs on client and server, but it is built for Minecraft 1.20.1 only, so it does not cover 26.2.
