Endless Dungeon balance and dying (a lot)

[llys]

Hello, I'm a new player.

So after some blood and sweat I managed to get one of my characters to about lvl 40 and have unlocked the Endless Dungeon. From the looks of it, it seemed like a nice sandbox to try some builds and character ideas and what not.
But, behold, just after spawning on the very first level of the dungeon i walk too far into the fog of war and just instantly die to 2 lvl 30+ ranged minions? I don't even have any gear yet, this is literally the first level... is this thing just impossible to clear without casting remote vision at every single corner, or am i just fantastically unlucky?
