First thing first I pick Ruele of Light from moonlight blessing since I already have her and hope to get 10 Galaxy coin.
but after I get all quest done and get Ruele there's no 10 Galaxy Coin...
OK that's the issue about missing information on the patch note!
Since I check here and found that if you get character from selector or get from galaxy shop it didn't count as summon.
So yes I already got Ruele from selector since a very longtime from ML Baal and Sezan got nerf in the first time
but How am I suppose to know that this gonna happen? no such information in the patch note of moonlight blessing.
"If the Hero is one that you already own, after fully unlocking the Hero by completing the required missions,
players will receive 10 Galaxy Coins as well." << That all there is
*Even when I finish all the quest and got Ruele and when summon cutscene appear
she didn't say a single word cause it's like I already have her...not a proper summon eh?
