Boot might seem unimpactful, but under the right circumstances it can save your life

I was playing Silent today, and was up against Slime Boss as the Act 1 boss. Fortunately, I'd taken plenty of frontloaded damage, and I managed to do a lot of damage by just throwing out attacks turn 1. Turn 2, I carefully did the math to see what I needed to play, and used two strikes to get him down to exactly 79 HP. Then I used Neutralize, because I knew that it would bring him down to 76 and set up the next turn perfectly.

So anyway, Boot can save your life under the right circumstances, if those circumstances are that you're Slime Boss and the player forgot they had the Boot.
