The only thing that I don't like about autopotion is that if they get you a 300+ blow (with jumps, monster attacks) and physical changing status attacks, you'll heal in a small quantity or get even petrified, and unless you heal with another method, you are just slowing their death. =/
But indeed, auto potion and blade grasp are the two of the five- best counters in the game.
*finish with out of topic*
For contuining to the topic, I only like counter tagged along with two blood swords, and a beef-up PA.
Or with the cheap but good excalibur-chaos blade with secret hunt.
