Be more precautious

Whenever exploring unknown places or hunting something for the first time, bring extra potions with you as a safety precaution. Avoid going to unknown areas without the necessary equipment. Always bring at least a rope, shovel and pick with you when exploring (or a Secret Service Quest reward). Some other tools may be required also, such as machete if you hunt around Venore, or a melee weapon for Dworcs. Stealth, dwarven, energy and other rings may also help in case you underestimate the area.

Remember to never leave your character (i.e. to go away from keyboard) in places that others will notice you. Even a low level could kill you if they know you aren't attentive to your character. And even in a Optional PvP world people can lure monsters at you or even push your character to dangerous places.
