Hey, thanks for the feedback!
The basic stats (str, int, agi, cha, mag) are just flat additions to base damage. The other stats scale with a square root, so it’s better to invest just enough to pass requirement checks.
Player health is always 10 clicks + bonus stamina. I'll have to make things clearer for sure.
As for the last encounter, that requires a very specific setup to beat since the map is still far from complete. Basically, you need to stack as much Magic as possible then take the Arcanophobia debuff which converts all Magic into 4× Intelligence and blocks Magic gain. Depending on your upgrades, you might need to get lucky with how many mandrakes you manage to dig up too.
If you want other games with similar gameplay, take a look at Reincarnated as a Dark Lord Before Taking Over the World with Power 999999999. I pretty much took the node idea from that one. There’s also Your Chronicle and Increlution on Steam too.
