Archlight Online Wiki

Late game you'll have to get into gem slotting to upgrade your gear into having more sustain or more damage.

Gems are a must for evolving in Archlight, each helmet, armor, legs, boots and weapon can have up to 7 slots for gems. Those slots can be opened by using Regrade Keys.
Gems are made by Jewelcrafting, and each gem have 2 possible effects.

New Gem Remover rolling system

It is now possible to use up to 10 Gem Removers at once, and choose the roll you want from these options. If you wish to use Gem Removers in this way, you will spend 10 Gem Removers even if you choose the second option from the list.

It will work as follows: when using the gems on your equipment, a screen will appear with several options for rolls (related to the amount of Gem Removers you have in BP), with a maximum of 10 options. When choosing one of the rolls, the amount of Gem Removers consumed will be equal to the amount of roll options that were presented.

Jewelcrafting currently offers 4 tiers of gems. Normal Gems, Charged Gems, Overcharged Gems and Surging Gems, each gem is stronger (min-max rolls) than the previous one. Below you will find possible builds (templates to direct players on how they can build. Your build can be different, its all up to personal preference.)
You can have as many gems of the same type as you want, but after 11 rolls of the same effect you will receive something called diminishing returns, these were made to prevent people from building up full damage and/or full resistance and either killing people instantly or becoming unkillable. You will receive the following penalties for each extra gem effect:
But hey, what do you mean exactly by penalty?
Answer: Once you hit 12 gems with the same effect, all of your gems on the last piece of gear will receive a -25% efficiency.

Gems Penalty
12 25% for each further one
20 35% for each further one
25 45% for each further one
30+ 55% for each further one
