It's no biggy... Was down to experience when doing a dungeon for the first time.
I didnt know some of the mechanics and inbound sight it was obvious I was getting it wrong.
There were a few grumbles and finally someone piped up and told me where I was going wrong in a near coherent set of words
Once I knew where I was going wrong, all went well and I got a commendation at the end!

I think the take away is to declare up front its my first time, and have a keyboard connected to the ps4 as typing on the joy pad is a nightmare!
