Anyhoo, when you stumble into enemies that clearly overpower you, you still can flee. If you step on three mines you didn't see, game over. I think that's the big difference. Although the counter-argument to that is when you create a character and you read that perception helps you "detect traps", I'd probably be wise to invest a few points in it and bump it a little along the way when you level.
I'm pretty sure 6 points (+ a possible item or trait boost) are enough for that particular area to reveal the first couple of mines.
I completed the whole cyseal map on Hard mode without stepping on a mine, my best character probably had 7. I don't think they overshot the danger here.
