1. This game is in english but they sometimes play korean chat to mess with us. It's like a secret chat to negate spoiler on story mode.
2. Graphics is good , game is turn based with speed as dominant attribute to get turn. Item has set bonus like MMO. Pretty standard with upgrade and so on.
3. No character gacha but u buy straight. It's super expensive. Some need other currency like real money or other in game currency.
4. At first it feel nice. but at some progress it feel heavy. Your unit will be severely underperformed and need to upgrade to prepare for next level.
Level up is slow. Exp potion is given a lot but it's still slow. Very slow. Awakening material also slow even for ur 3* unit at the beginning. The progress on ur team building is slow.
5. Awakening a character doesnt give much benefit. Your character will reset to lv 1, again level up is slow. Very slow... Your skill wont get much upgrade from awakening. You need skill upgrade material from a separate grind.
6. I abandoned this game because it's slow. Sorry guys..
