Snaga jewellery

[Siggesigge]

So, on dlvl 11 my Kobold Rogue had a "Superb treasures" level feeling and I decided to clear the floor. Yeah, you guessed it - dungeon book, and wrong class to boot. Lame!

a Necromantic Tome [Deadly Powers]
Found lying on the floor at 550 feet (level 11)

Cannot be harmed by Fire.

However, while clearing, a snaga dropped this little piece of jewellery for me:

d) a Ring of Speed <+6>
     Dropped by a snaga at 550 feet (level 11)
     
     +6 speed.

...How much luck did I just use up? What horrible stupid death awaits my poor Rogue now?

about 5 full games' worth of luck.
