TCOS Cheat: Safe zone on objects

In TCoS if mobs are chasing you, you can jump up on various objects and most of the time the mobs cant get to you. But mobs will not stop trying to attack you while up on the object either. So if a monster is chasing you, and there is a good treestump or boulder or something to jump on that isnt too small, most of the time the monster will not climb up after you. I my party had a boss mob start chasing us, out of habit we jumped on a large boulder so not to die. The boss mob could not get up on the boulder, and stayed there trying to attack us while we finally killed it with ranged attacks and spells. This works most of the time for normal mobs also. They very rarely follow up on the object, and when they have, you can jump down and jump back up and sometimes they wont chase up top the 2nd time.
