# Reward Pool
Reward Pool displays the total Essence Stones spent daily/weekly, with data available for the past 50 days and 50 weeks.
In SL:U, users can obtain Shadow Army cards by upgrading S-Rank Monster Cards.
Every Monday, 20% of the total Essence Stones spent in SL:U during the previous week is distributed to ‘Shadow Army cards holders’.
The reward calculation formula is detailed below.
## 1. Essence Stone Consumption Amount
