Trim Upgrade : Core
by XIYUE233
Trim Upgrade : Core turns the vanilla armor trim system into a progression layer, giving each trim its own combat and utility identity on Forge for 1.20.1.
What it does
The mod expands the armor trims already in Minecraft rather than replacing them, so the original trim themes stay intact while each one gains gameplay effects. Trimmed pieces can grant per-piece bonuses, and wearing a complete set can add full set effects. Active skills are tied to selected trim sets, so the same armor can serve different combat styles, mobility options, defensive setups or utility-focused loadouts.
Trims are upgraded in steps through the Trim Upgrade Table, using materials added by the mod, including Magic Crystals, Upgrade Gems and Miracle items. Trim Upgrade : Core is a Forge mod for 1.20.1, released under All rights reserved, and it must run on both the client and the server.
Key features

Each vanilla armor trim template carries its own gameplay effect, so trims no longer serve only as decoration.
Per-piece and set bonuses
Individual trimmed pieces add bonuses, and matching sets gain additional full set effects.
Active trim skills
Players select trim sets that provide active skills, including a mobility burst.
Upgradeable trim levels
The Trim Upgrade Table raises trim levels using upgrade gems and special materials.

Use cases
Building around a combat style
A player picks trim sets that suit melee, mobility or defense and upgrades only that armor.
Adding a progression layer to survival
Trims become a long-term goal, with crafted materials and upgrade steps that extend survival play.
Who it’s for: The mod suits survival players and server owners who expect armor trims to carry weight in combat, and who are willing to run it on both sides.
