I just recently started on sid story around 4 days ago, so personally I require the ways of getting sr sidians and to max fusion.
What can I understand and get is the following :
- Sidian change, farm 3*+ irregulars and use it to get higher star
- Forest, use jewels to purchase magic paper and obtain specific sidian
- Daily summon (occasional), gather 2400 jewels for four same sidians?
- Altar, create summon stone from atelier, farm the material from exploration's Irregulars
- Mileage, gather 600k points from exceptional and intruder
- Tickets, low chance to obtain sr sidians
- Gold summon (early monthly), extremely low chance to obtain sr sidian
- Other events
Is there any error or any other way? And it seem that getting sr is easy, but the cost/reward to get it is almost equally the same or harder.
