First, we need a list of preset goals.
- 30 pulls in Elemental Summon
- 50 pulls in Epic Hero Summon
- 80 pulls in Event Summon
- 100 pulls in Atlantis Summon
For each goal I can save a small part of my gems that I bought or I got from battles and missions.
The gems cannot be taken back from the savings account.
Also, some of the free rewards in gems from missions and battles could go directly in savings account.
