Lightning and meteorstrike at level 2 do not work effectively on the steel skeletons, since they have high resistance and a lot of hitpoints, especially the large steel skeletal warriors. A character under level 15 will be quickly ambushed and overwhelmed by a group of steel skeletons, unless equipped with excellent armor and weapon, and a number of medium charms. A survivor *can* just sneak through the dungeon at low levels, though many monsters also can notice hidden characters. Usually out in the open you can just run away, but in a dungeon it's probably more difficult.
