Looking at the shop its clear that there are no pay to win aspects. Quality of life global buff and cosmetics are all that's there besides skill reset. Especially when this game gets a bit more popular it will be a common for players to want to reset their skills when a meta develops for pvp or just pve. I believe it would be a good quality of life improvement to add a way to get them as they are likely something that could be EXTREMELY important to have a few of later on. I suggest offering it to a shop for a berries maybe 1-3k depending on how easy it is to acquire berries later on. It will also remove real money trades if that's something you are worried about as I see a lot of people advertising in the community discord about it.
