Basically i was killing stronger stacks with ease then ran into a stack that was the same strength but had 3 wildling shamans i think it was that cast fire attacks that hit all your units, basically my entire army was half dead by the time i got to move so i chose to use the escape item, problem is that on ai turn the ai stack attacks me so my army without escape got wiped out. That makes the item pointless. And it does have text saying it will teleport to the capital, if that is supposed to change then with the current 0 movement on battle the item should give 1 movement or move you away from the stack you are escaping from.
If an item that clearly states that it will teleport you to the capital and is meant for escaping battles does not do that then it's broken.
