I was a bit wrong about the Courier being useless (I know it got buffed anyway). I didn’t realise the top row of the shop has ‘columns’ - always 2 attacks 2 skills and 1 power. As the silent I went nuts on the power column picking up a bunch of caltrops, footworks and noxious fumes in one shop. Bird Faced Urn did tons of healing that game. Of course when I got to the third floor it turned out I had to fight the awakened one, whose second form ended up killing me (I was semi conservative at the start, using both malaises on the first form and only a few of my powers).
It was also a weird run for another reason. I got jewelled choker as a swap for my starting relic from Neow, then runic dome from the first boss, then there was nothing good to take from the second boss so I got sozu. This meant I always had at least 6 energy per turn but could only play at most 6 cards per turn. It was easy to trigger Panache.
