Is there a way to inscribe hands to avoid unarmed attacks?
I cast Sublimation of Blood and forgot to switch to weapon.

As a rule of thumb, if you can't do it in Nethack, you DEFINITELY can't do it in Crawl

I know almost nothing about Nethack but I guess the answer is "it's impossible in crawl".
I think it's possible to create a new setting option in init.txt but I hoped there is an easier way.
