Luck is a big factor. As for me, I never get a one on one encounter with anything.

Example: I start new character, go to fight first boss the Stag but as usual the Boss spawns and a fricken Troll want some action as well. So Im running my arce off and no stamina to be found , so im bobbin and weaving thru trees to stay alive. Usually once you get far enough from where the Boss and Troll spawn, they go back to that point and wait on you. But not for me, they chased me all over that darn Island and never gave up.

So yeah Luck is your friend, but not mine. LMAO
