Leveling up Soul Crystals in Lineage 2 involves a unique process where players must use these crystals to absorb the souls of specific mobs (monsters) to upgrade their level. This process is known as "soul crystal leveling" or "soul crystal enchanting."
Lets see how it works:

Obtaining a Soul Crystal: First, you need to obtain a Soul Crystal. These can be acquired through various means like quests, monster drops, or purchasing from other players.
Identifying the Right Mobs: Each Soul Crystal can only be leveled up by defeating specific mobs. These mobs are typically higher level and are known as "raid bosses" or "mobs with a blue aura." The correct mob for leveling a crystal often depends on the crystal's current level.
Party Requirements: Typically, you need to be in a party to level up a Soul Crystal. Only one crystal can be leveled up per mob, so if multiple party members have crystals, only one will receive the upgrade.
The Last Hit: The most crucial part of leveling a Soul Crystal is the last hit. The player who wants to level up their Soul Crystal must deliver the final blow to the mob. In some versions of the game, it's required that the player with the crystal also has to have the killing blow, or in other cases, they just need to be in the party and participate in the fight.
Crystal Levels Up: If all conditions are met (right mob, last hit, etc.), the Soul Crystal will level up. This is indicated by a change in the crystal's name and possibly its color.
Failure and Risk: There's a chance that the process might fail. Depending on the game version and specific rules, a failure can result in different consequences, like the crystal not leveling up, or in harsher scenarios, the crystal could break or be lost.
Max Level and Further Use: Once a Soul Crystal reaches its maximum level, it can be used to add special abilities to weapons.

The exact mobs, crystal types, and success rates can vary based on the version of Lineage 2 you're playing (like Classic, Private Servers, or Retail). It's always a good idea to consult a current guide or database specific to your server's version for the most accurate and detailed information, including which mobs to target at each crystal level.
