Very good game been playing for 2 years now . I see that a lot of ppl complain about , how hard the game is . Well in the begining it does, but i want to remind some of you that YT guides is out there , so if you get stuck go watch some of them .
Game is very generous with the Gacha within 50 pull you will get a 6* ( 2% drop rate ) , if your luck is bad and didn't get a 6* in the 50 , it will count into 4% drop chances per 6* , the next 50 pull . Every 50 pull if your luck still suck it will keep counting up , when you get a 6* it will reset back to 2% . Honestly tho i would say that the begining, you don't need any 6* just use 1 or 2 that the game gave you ( within the first beginner banner ) , then lv up all of your 3 to 4* in your team . So yeah just save all of your resourse that you get , or roll 1 or 2 more chacracter that you like . ( btw the 1 and 2* in the game is really good too so don't ignore them )
Also if you're now a Mid game to End Game player or have a full team at E1 lv 50 ( Promotion 1 lv 50 ) , with Base build to lv 4 , with 3 or all of your Factory at lv 3 . This is the MOST important part of the gacha and , why this game is the best is that with lv 3 Factory you , can start generate your own in game Gacha resourse . With the resourse you make, you can do more gacha roll without needed to spend money on the game to pull them ( unless you wanted to , who to judge right ? ) . If you are new to the game i suggest that you built a 2-4-3 base ( 2 Trade post , 4 Factory , 3 Power plant ) , then
2-5-2 ( if you have upgrade all of other part of the base to lv 3 ) .
