Hey, wellcome to EA, there are a lot of way ti get ceraniums, ill list some, if i miss something i hope that somebody else will correct me:
- Kata/Dana and Abyss siege
- MKK (the 3 upper abyss fortress instance, Miren, Kysis and Krotan, you can do that only if your faction got the fort 1x ceranium x fort)
- OB (Ophidian Bridge the 6 men pve instance, last boss will drop a pouch with ceranium fragment or a low chance for ceranium medal, you can do x4 x week)
- EB (Eternal Bastion the 24 men pve instance, 1 x day with 4x ceranium if rank s)
- Sillus solo instance 1x day will give 1 ceranium if rank S, there are a lot of guide on yt that can help you with rank
- You can exchange mitril medal (1x) and ceranium fragment (10x) for a chance to get 1x ceranium medal
- Silona instance 6 men 1x day will give 1 ceranium if rank s (im not sure about that, didnt do that instance from a long time)
Correct me guys if i miss somethings.
