First of it is a gacha game so players who spend will be a lot powerful than you
sadly there are costume and personal weapon that are lock in pay wall
getting max rarity upgrade of each character is not in a paywall yes you can get every unit that you have unlocked "the word UNLOCKED" can be a max star character with just playing daily
sadly to say weapons gear are in pay wall currently but we do have default legendary "highest tier" weapon for you to use well it is better than nothing

game mode itself / story is very interesting if that is your umm type of game
the story will branch out depending on your choices and dialogues
so each choice creates a different timeline / ending
playing story does not consume stamina but requires you to use a key
you can get keys from events / weekly shop for free
after you finish a critical or major " critical / major " point of event it will ask you for another key to continue onwards to the story
while in story mode you can also build up your characters to have different skill and combine / use them in different classes you can only bring up to 3 skill and 1 reflex skill
this is where the rougelike system comes in because you dont know what skills you will get

each character has 2 different skill tree you can combine skill tree 1 with skill tree 2 to get a unique character or characters for specific occasions

most of all i enjoy it medieval rts
