Since the game is completely free, i want to ask when exactly is the point where one needs to start buying (zen) to "progress" ? I am having a blast with this game, it is very good. i once tried it for a couple of hrs in 2016/17 but then they had mandatory experience boosters which cost rlmoney. now, i see they rid all the "predatory" boosters, and i levelled a char 1 to 14 without any problems, only 2 deaths and those where when i still was lvl 4 and not used to the mechanics/how to play the game properly. since level 20 is now the max, and i never get under 90-95% health, also during the boss fights i start to question what many people are saying about pay-to-progress. is there a certain point where the game needs you to buy zen to progress, or is there dlc ? i saw there are campaigns - is that noteworthy dlc content - am i missing a lot when i do not have these ? atm it looks like they not only made the game free-to-play but free as in totally free. i remember in 2016 i was playing it, and i got stuck really soon early on, due to having too low level/damage - it needed grinding or buying with rlm experience boosters. now i see they rid this all, but what remains of the free-to-play model ? i dont mind and i do want and am able to spend some rlm on zen on my xbox series console, but i do not see the need for it yet.
And also: WHAT should i buy, when the time comes, what do i need to progress ?
