Q: When my pet was Level 84, I used a Phantom Exp Stone which can deposit 10,000,000 EXP. For some reason, it can only deposit 6,791,086 EXP when my pet became Level 85... Why is this?
A: The amount of EXP that a Phantom Exp Stone can deposit is decided by the amount of EXP that a pet needs to level up. In Angels Online, this is normal when a pet is Level 80-90. For example: A Level 100 character may require less exp to reach 101 than a Level 99 character needs to level up to 100.
