When you give this token to NPC Einhar Van Hellscar in Oren's Castle Town, you'll get a significant amount of EXP and SP as a reward.

The EXP and SP you get depends on how high your character's level is.
The best bonus is for characters who are level 40 to 81.
After level 81, the EXP and SP you get goes down a lot.
