I Like To Watch Achievement/Trophy Guide
This achievement follows similar steps to my previous guide for the following achievement:
In ACT 2 you will be given the ability to start dominating the minds of captains and turning them to your side. When you have this ability, head up to the fortress and kill one of the two warchiefs then command one of your captains to Infiltrate
the now dead captains position. This will give you a mission called Infiltration
which will require you to simply sit there and watch as your captain fights against another captain and there is no possibility for you to get involved. I would recommend having a higher level captain go in as sometimes the enemy captain can roll up with bonus minions.
Here is a video of me unlocking it:
