I had not seen this mentioned elsewhere, so a small tip for not getting blown to pieces from your own wands when you are looked upon favorably by the god of fire, machines and weaponry:
If you look at the
materials each wand is made of, there are three wands that are made of metals that Loricatus can harden. Two "attack" wands that can make your life short(er) when they get blown up, and one utility wand that you probably want to have handy at all times.
So harden up those / of haste, / of striking and those / of fireballs. It might (temporarily) save your life!
(long time nethack player, slightly less longtime crawl player, wands breaking is always a tragedy)
