This tip is for those playing a new Death School character in Wizard City.
Many enemies in Wizard City (and elsewhere) have 235 health. Ghoul (Level 5), Deathblade (Level 7), and gear that totals +8 Death power or more (such as Troubled Helm, Martyr's Raiment, and Boots of the Adverse) will do exactly 235 damage and defeat these monsters, while returning 117 health to the wizard. Note that it won't work for enemies with resistance to Death spells, or any who can cast Death Shield, but I don't know of any in Wizard City itself with 235 health that have that.
I also recommend that you get a Swoping Necklace with its Storm Bats spell for the bosses in the Death school.
