Level requirements

The table below shows how much materials do you need to upgrade the levels of your characters. While from levels 1 to 201, you will need to use Mana Crystals every 20 levels, starting from level 202 you will need to use them every level.

Mana Crystal needed to reach level:

• Level 11 - 10 Mana Crystal
• Level 21 - 50 Mana Crystal
• Level 41 - 100 Mana Crystal
• Level 61 - 250 Mana Crystal
• Level 81 - 500 Mana Crystal
• Level 101 - 1 200 Mana Crystal
• Level 121 - 3 000 Mana Crystal
• Level 141 - 6 000 Mana Crystal
• Level 161 - 12 000 Mana Crystal
• Level 181 - 24 000 Mana Crystal
• Level 201 - 30 000 Mana Crystal

Also, it seems that compared to most idle games, in Eversoul the Sync Device doesn't transform, allowing you to level it instead of the characters, but you have to continue to level each character separately.
