Soul Crystal Engraving is a feature unlocked when the player reaches level 35. Soul crystals are used to raise the level of the soul engraving which increases the bonus of socketed gems.
Mechanics
The soul engraving icon is found in the inventory screen which is accessed by clicking on the character's portrait in the upper left corner of the player's UI. The Soul Engraving icon's location is shown by the corresponding picture.
At level 35, the player will receive the usual level up pop-up window, and underneath the "Unlocked" will be written Soul Engraving. Soul engraving allows the player to engrave (or more accurately, use) Soul crystals to increase the level of soul engraving. In turn, this increases the bonus of socketed gems. Every level of engraving increases the effects of socketed gems by 2-4% regardless of the gem's type or level.
In the soul engraving interface, the player is shown an experience bar and the current level of
engraving. Also listed are "current level" effect and "next level" effect. If a player has soul crystals, then the amount in inventory will show and the player will be given the option to engrave the crystals. Note that the player is given the option to manually type the number of crystals to engrave, meaning that if a player wished, they could engrave only some of the crystals they possess.
At the same time engraving unlocks, players are given a quest to increase the level of their soul engraving from level 1 to level 2. This requires 10 soul crystals. Upon completion of this quest, the player will be rewarded 100 soul crystals which, if engraved all at once, will increase the player's soul engraving level to 4.
