It's been a while since I read that page; fun to come back to it now that I actually know what I'm doing in Crawl.
It has some...interesting...bits:
"most forms of magic increase hunger to the point where a ring of sustenance is a prized possession."
"It is entirely possible to abandon your god if you no longer find them useful, and/or to choose a new god. This will usually make the god you abandoned angry at you; however, it is entirely possible to survive their wrath until it runs out. Doing this with the necromancy god is an explicit part of one strategy guide for a Mummy Wizard."
"The latter is also available in form of a healing wand. More favored than potions because they cannot be destroyed, but exceedingly rare and
difficult to recharge." (emphasis mine)
"The Healer class is actually pretty effective at fighting to begin with, as they begin with skill in unarmed combat."
"The infamous Sigmund can show up as early as the first floor, or as the first enemy for that matter"
"Sometimes you get a dragon hide on the first floor, sometimes you get a dragon on the first floor."
Good stuff. <3
