Arcane Tower fight was way too easy last night

I'm playing co-op with a friend, streaming it. Last time we were in the Arcane Tower, we realized the Sussar flower caused the automatons problems.

Last night, we decided to use this to our advantage. We obained 5 Sussar blooms. 3 from the tee by the Hook Horrors and 2 from the backyard of the tower.

We talked to the big guy and got the ring. No problem. THEN, I ran around and dropped a flower in front of all of the archers. I had one left on me. I'm a Swashbuckler Rogue, so it doesn't hurt my fighting.

It was SO EASY. I stood next to the big guy and we just hit him until he went down. Then we took out the stunned archers.

Wanted to share this, as it was so fun to do. I don't look for exploits too much, so I if this is well known, I apologize :)
