Here is it (from this page (

When a third class character reaches level 85, the ancient Giant King Hermuncus sends a message directly to the mind of the hero in the Material Plane, who can release him from his seal. The character can check the message on the dialog window.
The character who has the "Pact of Righteous Path" item can Awaken at the ancient Giant statue located in the "Reliquary of the Giants":
You can obtain the "Pact of Righteous Path" item by completing the "Seize Your Destiny" quest.
The Reliquary of the Giants, where the ancient Giant statues are located, can be reached freely through Gatekeeper Rachel in Talking Island Village.
When a character Awakens, all previously learned skills are replaced by new skills. The character receives SP and a certain quantity of Essence of the Giants according to the level of skill enchantement.
A character that received the power of the ancient Giant heroes Awakens, and obtains a chest that contains their powers:
Five 100,000,000 SP scrolls
A class-specific cloak
Two weapon attribute change crystals (S-Grade)
Five Elixirs of Blessing.
A main class that completes Awakening can start to use a new means of transport, "Jump." However, characters in a chaotic state cannot use Jump.
The update issues all characters who are level 76 or above with a single "Stone of Destiny." A character that has both "Stone of Destiny" and "Pact of Righteous Path" can Awaken into a different class.
E.g.: A Maestro normally Awakens as a Tyrr Warrior, but with both "Stone of Destiny" and "Pact of Righteous Path" it is possible to Awaken as a Sigel Knight, Othell Rogue, Yul Archer, Feoh Wizard, Iss Enchanter, Wynn Summoner or Aeore Healer.
The "Stone of Destiny" disappears even if you Awaken as your designated class.
The "Stone of Destiny" will only be granted once at the time of the update.
