In Trove, players can upgrade their class even further using Gems. These Gems will allow players to add additional stats, buffs and ability modifications to their class to enter higher Uber worlds and/or take on the Shores of the Everdark World. This mechanic of upgrading items was introduced in the Mantle of Power Expansion. This system however takes quite a while due to the sheer number of RNG put into getting the perfect Gem that suits a player's playstyle.

Upgrading Gems

Collecting Gems

Gems come in a variety of elements type each with its own set values and rarity. Gems can only be obtained through Gem Boxes which can be obtained by completing Lairs and Dungeons in Uber leveled worlds; higher Ubers will give higher rarity gems:

Uber 1-2: Common Gem Boxes will commonly give Common Gems, uncommonly Uncommon Gems, and rarely Rare Gems.
Uber 3: Uncommon Gem Boxes will commonly give Uncommon Gems, uncommonly Rare Gems, and rarely Epic Gems.
Uber 4: Rare Gem Boxes will commonly give Rare Gems, uncommonly Epic Gems, and rarely Legendary Gems.
Uber 5: Epic Gem Boxes will commonly give Epic Gems, uncommonly Legendary Gems, and rarely Relic Gems.
Uber 6: Legendary Gem Boxes will commonly give Legendary Gems, uncommonly Relic Gems, and rarely Resplendent Gems.
Uber 7: Relic Gem Boxes will commonly give Relic Gems, uncommonly Resplendent Gems, and rarely Shadow Gems.
Uber 8: Resplendent Gem Boxes will commonly give Resplendent Gems, uncommonly Shadow Gems, and rarely Radiant Gems.
Uber 9: Shadow Gem Boxes will commonly give Shadow Gems, uncommonly Radiant Gems, and rarely Stellar Gems.

Adding/Removing Gems

All gems can be upgraded at the Character Sheet by pressing the C key. In this menu, there will be a gems tab where you can equip and upgrade gems. Player can equip a gem by dragging the gem to an available gem slot. More gem slots will be available as you level up you class by gaining experience. Here is a list of when certain gem slots become available:

The First Normal Water Gem slot is unlocked at level 10.
The First Normal Air Gem slot is unlocked at level 13.
The First Normal Fire Gem slot is unlocked at level 17.
The Empowered Water Gem slot is unlocked at level 21.
The Empowered Air Gem slot is unlocked at level 23.
The Empowered Fire Gem slot is unlocked at level 25.
The Second Normal Water Gem slot is unlocked at level 27.
The Second Normal Air Gem slot is unlocked at level 29.
The Second Normal Fire Gem slot is unlocked at level 30 (Max Level).

You can also unequip/unsocket a gem from this menu. To do this, drag the gem from your gem tab to your inventory, however unsocketing gems has a Re-Gemerator cost. It is not recommended to switch/share Gems between classes because of the cubit cost of the Re-Gemerators. Have gems for each class to prevent using up cubits from sharing gems.

Upgrade System

In the same menu, you can upgrade gems to add additional stats, boosts, and power rank for your class. For every attempt at leveling a gem, you need Gem Dust and Flux for upgrades. The dust must be the same type as the gem in order for the upgrade to work (i.e. you cannot use Air Gem Dust to upgrade Water Gems, only Water Gem Dust can upgrade Water Gems). The cost of Dust and Flux will increase for every successful level on the gem as well as the chance of the gem to become cracked. If a gem happens to become cracked, it can still be used to boost stats but cannot be upgraded until it has been fixed. To fix a cracked Gem, you must purchase a Re-Gemerator at the store (with a cost of 500 Cubits) and use it on the gem as if you are upgrading it. Cracked Normal gems will need just one Re-Gemerator while Empowered Gems will take two.

Leveling Boosts

As the level of a gem is increased, the cost in Flux and Gem Dust is increased, the chance to crack is increased, the chance for a successful level-up is decreased and the number of attempts until the Gem Karma triggers is increased.

There are 4 different boosts that can happen when successfully leveling up a Gem:

  • Small Boost (levels 2-4, 6-9 and 11-14)

5 small increases for each existing stat, +15 PR when 3 stats.

  • Moderate Boost (levels 16-19 and 21-24)

10 small increases for each existing stat, +30 PR when 3 stats. (equals 2 Small Boosts)

  • Moderate Boost+ (levels 20 and 25)

25 small increases for each existing stat, +75 PR when 3 stats. (equals 5 Small Boosts)

  • Large Boost (levels 5, 10 and 15) The next successful level-up will increase a single randomized stat value by a much larger amount than usual. The value of this increase is random (50%-100% 100-200 extra pr) on lesser gems, but fixed for Empowered Gems (always 100%, 200 extra pr). If the gem does not have 3 stats already, then one more stat will be added instead of boosting an existing stat. The gem cannot gain more than 3 stats.

When do you get more stars on your gem?

Stars on gems are simply an indication of Power Rank:

Stars Power Rank
* 210+
** 375
*** 700+
**** 1033+
***** 1350+

What are the best possible Gems?

Power Rank Stellar Emp. Stellar
Gem level 1 (3 stats) 700 600
Gem level 2 (3 stats) 715 615
Gem level 3 (3 stats) 730 630
Gem level 4 (3 stats) 745 645
Gem level 5 (3 stats) 945 845
Gem level 6 (3 stats) 960 860
Gem level 7 (3 stats) 975 875
Gem level 8 (3 stats) 990 890
Gem level 9 (3 stats) 1005 905
Gem level 10 (3 stats) 1205 1105
Gem level 11 (3 stats) 1220 1120
Gem level 12 (3 stats) 1235 1135
Gem level 13 (3 stats) 1250 1150
Gem level 14 (3 stats) 1265 1165
Gem level 15 (3 stats) 1465 1365
Gem level 16 (3 stats) 1495 1395
Gem level 17 (3 stats) 1525 1425
Gem level 18 (3 stats) 1555 1455
Gem level 19 (3 stats) 1585 1485
Gem level 20 (3 stats) 1660 1560
Gem level 21 (3 stats) 1690 1590
Gem level 22 (3 stats) 1720 1620
Gem level 23 (3 stats) 1750 1650
Gem level 24 (3 stats) 1780 1680
Gem level 25 (3 stats) 1855 1755

As you can see, the stellar emp. gem has a power rank difference of 100 pr per level compared to the normal stellar gem, due to the fact it has a random ability (ex. spirit surge) that comes with the empowered gem (this adds 100 pr to the gem)
