Hello everyone. This game is not definitely pay to win. You can reach max lvl easily and you can be strong player without spent any money. But takes a lot of time. I play about 9 months and Im not neither in half of all options to power up my character.
Money are really needed only for "reforging" (to get better secondary equip stats), but u can play without this too, because only 2 of 5 stats are really important to get strenght. These stats can be reforged without money, I did it many times.
If you dont need to be best of the best, this game is totally free to play.
p.s. enjoy playing !
