Overflow Experience is a feature introduced in Module 3: Curse of Icewind Dale. After a character reaches the maximum level of 70, extra experience accumulates for rewards.
Every 1,785,000 experience, the character receives a random award, which no one knows how to open to this day on PC because there are no guides on how to do this. It includes:
A chance of:
- An extra Power Point that can be used to rank up powers (Only 53 extra Power Points can be earned)
And one of the following:
- 10 Account-bound [Tome of Companion Experience] and 5 Account-bound [Tome of Experience]
- 5 Rank 5 enchantments
- 5 Rank 6 enchantments
- 1 [Flawless Sapphire]
- 1 [Black Opal]
- 30,000 Rough Astral Diamonds
