NO!!! I was level 23 (4 trees), I ran around ("flew" with the door in the book) on the map: 4 temples of some kind (+6 to each stat) – that's already +24, and an artifact +10 strength -2 knowledge, which means 34, +2 START + about 5 wheels.
So, 41 without taking the level into account!
Temples give +2 to stats... slow down...
And don't forget about magic!!
And we remember it and have already mentioned it...
