I meant for it to be auto-hit, not auto-kill, when I suggested it. It was natural to think people in Hell die slower than in real life, even if only to prolong their suffering.
So, I suggest near-fatal blows to be allowed every few posts, but fatal blows must be discussed with the other user.
That way people can randomly attack, making interaction easier and more fun due to the slight randomness of it all.
Of course, I suggest not doing it during critical moments in the rp, but at random times it can be very useful to keep the rp going and inspire others.
