Wisps effects not consistent in-game with Affliction page.

In-game, it says Primal Wisps empower enemies with Currency rewards.
The Affliction page on the main site says Primal Wisps are giving Increased Rarity.

I've yet to verify the other ones.

Edit:
Vivid Wisps in-game: Item Quantity
Vivid Wisps on website: Currency

Wild Wisps in-game: Item Rarity
Wild Wisps on website: Item Quantity

Primal Wisps in-game: Currency
Primal Wisps on website:Increased Rarity

It's hard to tell which one is correct while playing the League.
