Mentor System

The Mentor System is a great way to level up in Lineage II!

A character that is below level 85 can arrange a Mentoring contract with another character on the same server that is Awakened. The contract-bound characters gain powerful XP-boosting buffs when both Mentor and Mentee are logged in at the same time.

This page explains all about the Mentor System, but you can also find this information in-game by speaking to a Mentor Guide NPC in any major town.

Powerful buffs for both Mentor and Mentee!

Both Mentor and Mentee automatically receive useful buffs when both characters are logged in.

Who Can Be a Mentor or a Mentee?

  • To be eligible to become a Mentor, a character must be Awakened. A Mentor can take on a maximum of three Mentees at the same time.
  • To be eligible to become a Mentee, a character must be below level 85. A Mentee cannot also be a Mentor. A Mentee can only have one Mentor.

How to Get a Mentee Certificate

  1. Level up a character to level 85.
  2. After Awakening after you reach level 85, you will receive the Mentee Certificates in the mail.

Creating a Mentor Contract

Mentee Instructions: Only an aspiring Mentor can initiate a Mentor Contract. Characters that are looking to become a Mentee can advertise that they are looking for a Mentor by shouting in a town, asking their clan, or posting on the forums. Once you find an eligible Mentor, have them invite you into the Mentor Contract. When they invite you, you will see an invitation window. Click Accept to create the contract.


Mentor Instructions: A contract can only be created when both characters are logged in. To create a Mentor Contract, the aspiring Mentor must do the following:

  1. Open your System Menu, then the Friend Manager, and click on the Mentoring tab.
  2. Click on the + button to add a Mentee.
  3. You can browse the server for eligible Mentees that are online by using the Mentee Search tab and sorting by level range. The search results will show all characters below level 86 that have a Mentee Certificate, are not on a subclass, and do not already have a Mentor. If you already know the name of a potential Mentee, you can enter their name into the Character Name box, and click Add to list. This sends a Mentor invitation to that character.
  4. When that character accepts the invitation, they officially become your Mentee, and you become their Mentor. As you are both logged in, you both immediately receive the beneficial buffs from the Mentor Contract.

Both Mentor and Mentee are free to cancel the contract at any time. After a contract is canceled, the Mentor can make a contract with a new Mentee after two days. A Mentee receives no penalty for cancelling a contract; the Mentee can accept a new contract immediately.


Please note that the Mentoring tab of the Friend Manager window is only visible to characters who are eligible to be Mentors, and to Mentees who are in a Mentor contract.

Mentee Marks

Mentors can help Mentees level up and earn rewards at certain level-range milestones. Specifically, at level 40, then level 50, and then every level after that, Mentors receive a varying amount of Mentee’s Marks in their mailboxes. Mentors can use Mentee’s Marks to buy various items from the Mentor Guide NPC. Available items include but are not limited to:

  • Soul Crystal Changing Stones A- through R95-grade
  • Attribute Changing Crystals S- through R99-grade
  • Enchant Armor and Enchant Weapon Stones, which improve your odds of successful item enchantment
  • Super 60 and Super 150 Attribute Stones of all elements
  • Superior Giant's Codex
  • Elixir of Blessing


A Mentee graduates from the Mentor Contract when the character reaches level 86. At that time, the Contract is concluded. The recent Mentee is eligible to create a Mentor Contract one day after Awakening. Recent Mentees can exchange their Mentee Certificates for 40 Diplomas by speaking to Mentor Guide NPCs, which can be found in all major towns. Displomas are used to purchase R-grade items from the Mentor Guide NPC.
