Here's a few things that I've noted that might be worth adding:
In section 0.2.2 under the discussion of alignment, I think it would be worth mentioning that killing certain types of monsters have substantial effects on the PC's alignment. In particular, killing blink dogs and especially white unicorns is quite chaotic, even if the monsters are hostile. Killing certain chaotic beasts draws the PCs alignment towards lawful--I don't have a complete list, but it can be easily checked with the Law skill, but notably most dragons, daemons, and grues, as well as some giants (fire/frost giants for sure), steel golems, most chaos monsters, etc. I believe this works all the way up to level 50, although it may be that as you get higher in level, you need stronger monsters to change your alignment--haven't checked that part.
Your god will cure sickness (and possibly other conditions--not poison or blindness) when you sacrifice any amount on an altar, if your piety is respectably good (very close for sure). The same effect can be experienced by lawfuls using whips, on some occasions.
The disarm traps skill seems to give small amounts of experience under successful application--this may be the only way to gain experience without killing anything.
In 0.6.1, being Strained or Strained! definitely does not abuse dexterity, although it does increase food consumption. Being Overburdened does abuse dexterity quite severely, however. Although it isn't terribly convenient, spending large amounts of time while blind seems to train perception.
Poison hands corruption does not prevent the PC from 'U'sing herbs such as spenseweed, or doing alchemy.
In 0.14.6, I believe that at least the Candle starsign has been quantified explicitly. My memory is that it worked out to 1 HP every 8 turns, but I'm sure someone else can confirm. It is considerably better than the maxed out healing skill.
In, 0.14.9, I think the values quoted for seven league boots are incorrect. Blessed seven league boots reduce base walking speed from 1000 to 500, uncursed from 1000 to 750. I think cursed are 1500. The effect is a bit more complicated with other modifiers in place: long stride + 7lb reduces movement speed to 487, for example.
Hoping to win with every class, doomed. Archer, Barbarian, Bard, Beastfighter, Druid, Elementalist, Farmer, Fighter, Monk, and ULE Priest down.
