The Gem Mastery Test Center is a dedicated testing environment where players can experience the full Gem Mastery system without the usual time investment required on live servers. Everything you need — crafting materials, gems of every type and tier, and XP tomes for instant progression — is available for free from vendors located near the test center spawn point.
This page explains how to get set up and what resources are available to you.
Six vendors cover everything you need to fully test the Gem Mastery system. All items are free.
| Vendor Name | What They Sell |
|---|---|
| Gem Mastery Necklace Materials | All crafting ingredients for the Gem Mastery Necklace |
| Gem Mastery XP Tomes | XP tomes for instant level progression |
| Gem Mastery Vendor - Ruby | All Ruby Mastery Gems (every bonus type) |
| Gem Mastery Vendor - Sapphire | All Sapphire Mastery Gems (every bonus type) |
| Gem Mastery Vendor - Topaz | All Topaz Mastery Gems (every bonus type) |
| Gem Mastery Vendor - Obsidian | All Obsidian Mastery Gems (every bonus type) |
The Gem Mastery Necklace is crafted via the Tinkering skill (100 skill required). No recipe scroll is needed — the recipe appears by default in the Gem Mastery category of the Tinkering menu.
Purchase all ingredients from the Gem Mastery Necklace Materials vendor before opening your Tinkering menu.
| Ingredient | Quantity |
|---|---|
| Shard Essence | 250 |
| Valorite Ingots | 100 |
| Diamonds | 30 |
| Sapphires | 30 |
| Rubies | 30 |
| Topazes | 30 |
The vendor stocks 9,999 of each ingredient. Once crafted, the necklace will appear in your backpack. Double-click it to open the Gem Mastery UI, or right-click it and select Activate to equip and enable bonuses.
On the test center, you can gain Gem Mastery XP in two ways:
XP is awarded automatically when you deal damage to and kill monsters, exactly as it works on live servers. You must deal at least 5% of the monster’s total damage to receive XP, and stronger monsters award more XP.
For faster testing, purchase XP Tomes from the Gem Mastery XP Tomes vendor. Double-click a tome to consume it and instantly add the listed amount of XP to your account. Your level display updates immediately.
Known test-center quirk: after a big tome jump, newly-unlocked slots may not accept gems until you relog once (the account record write needs to settle). If “Install Gem” won’t socket right after using a tome, log out and back in. (XP tomes are a test-center-only convenience and won’t exist on live servers, where levels are earned gradually by killing monsters.)
| Tome | XP Granted | Approximate Level Reached |
|---|---|---|
| Mastery XP Tome: 1M | 1,000,000 | ~Level 1–2 |
| Mastery XP Tome: 10M | 10,000,000 | ~Level 10 |
| Mastery XP Tome: 25M | 25,000,000 | ~Level 14 |
| Mastery XP Tome: 50M | 50,000,000 | ~Level 20 |
| Mastery XP Tome: 111.75M | 111,750,000 | Level 30 (Max) |
Gem Mastery progress is account-wide. XP earned on any character — including via tomes — applies to your entire account.
Each level unlocks one new gem slot. Below are the cumulative XP totals required to reach each level:
| Level | XP Required | Level | XP Required |
|---|---|---|---|
| 1 | 100,000 | 16 | 31,600,000 |
| 2 | 450,000 | 17 | 35,700,000 |
| 3 | 1,050,000 | 18 | 40,050,000 |
| 4 | 1,900,000 | 19 | 44,650,000 |
| 5 | 3,000,000 | 20 | 49,500,000 |
| 6 | 4,350,000 | 21 | 54,600,000 |
| 7 | 5,950,000 | 22 | 59,950,000 |
| 8 | 7,800,000 | 23 | 65,550,000 |
| 9 | 9,900,000 | 24 | 71,400,000 |
| 10 | 12,250,000 | 25 | 77,500,000 |
| 11 | 14,850,000 | 26 | 83,850,000 |
| 12 | 17,700,000 | 27 | 90,450,000 |
| 13 | 20,800,000 | 28 | 97,300,000 |
| 14 | 24,150,000 | 29 | 104,400,000 |
| 15 | 27,750,000 | 30 | 111,750,000 |
On the test center, all gems are available for free from the four gem vendors — one per material tier. Each vendor stocks every available bonus type for that tier, allowing you to test any combination without relying on random drops.
Gems also still drop from monsters during normal test play, giving you the opportunity to verify the loot system is working.
There are four gem materials, each with a different power multiplier applied to the base bonus value:
| Material | Multiplier | Typical Source (Live) |
|---|---|---|
| Ruby | 1.00x — standard | Common monsters |
| Sapphire | 1.20x — enhanced | Uncommon monsters |
| Topaz | 1.40x — superior | Rare monsters / bosses |
| Obsidian | 1.75x — corrupted | Elite monsters / raid bosses |
For example, a gem with Melee Ignore Armor Chance gives:
Every gem installation costs gold, based on the gem’s material tier. This cost applies on the test center just as it does on live — make sure you have gold available before installing.
| Gem Material | Gold Cost |
|---|---|
| Ruby | 30,000 gp |
| Sapphire | 60,000 gp |
| Topaz | 90,000 gp |
| Obsidian | 150,000 gp |
To install a gem:
Gems can be removed at any time — click the gem slot button in the Gem Mastery window and confirm. The gem is returned to your backpack intact with no removal cost.
Every bonus type available in the live Gem Mastery system is sold on the test center vendors. The bonus type determines the passive effect the gem provides when installed.
