It all depends on who attacked you and where.If, for example, you went to the mountains for the first time in iron armor, and wolves attacked you there, then the smartest thing you can do is to escape into the portal as quickly as possible, if the portal is far away and you don't have time to reach it, then look for the coolest stone and try to climb it.In any other case, the wolves will eat you :).Well, if you walk in fully pumped Troll armor and with a good bronze weapon and you were attacked by creatures from the Dark Forest, then it should be a holiday for you :), simply because you will easily repel this attack, while collecting resources from the killed creatures.
