If you kill the enemy, I assume you cannot place next to them? Or does the place occur before the damage is dealt? Not sure if it works the same as Valkyrie.
Excellent question! I played a game with our friend @Tribulus when his own interpretation of Ohohoh Surprise is that he purposely inflicted less than 2 so that my character would stay in the Hexadome so he could gain the full distance of the "Place." That interpretation would as you say be consistent with the ruling on Valkyrie's Charge. Another great question for @-V- .
You follow the tactic step by step, if by the time the target is already in the Infirmary, then Final Boss won't be able to place himself next to him.
So, we always follow Tactics in order step by step? Could we get that clearly stated in the FAQ perhaps?
Please, don't. Nobody was born knowing all. To make an effort to learn is by far more valuable than being a know-it-all
