No.
At the end of the game, level 53, my warrior's vitality and mana were 1260 and 574 (444 and 30 without equipment bonuses). Primary stats were up to 150 (112 without equipment), resistances 110 (25) and armour 484 (0).
I only used one charm in the game, so there was room to boost my stats more, if the end game wasn't already fairly easy given my level and equipment.
Testing something with sight range, a sight bonus of 1000 cleared much of the fog of war from the final map area. Trying to equip a second ring with a 1000 sight bonus crashed the game.
