Spell check doesn’t necessarily catch words that are spelled correctly but chosen incorrectly. Here’s a list of some of the most common I’ve found in my editing experience. (Written in a certain vein, because vampires need proper grammar too.)

What will be the effect (result) of this dry, hot summer? More than these lost barley rows, the drought will affect (influence/cause a response) the substance of my blood, my ability to quench your constant need.
(Usually, “effect” is the noun, and “affect” is the verb; however, “effect” is sometimes used as a verb, as in, The drought effected (to bring about) great change in my body. And sometimes “affect” can be used as a noun, as in, He affected (assumed) a wry humor that belied his concern at the loss of blood.)

Before composing my letters of consolation on this vibrant green stationery (writing paper), I must find a table more stationary (motionless, unmoving) than these skeletal remains of my month-long feast.
They’re (they are) forever dancing up there (in a place), all these black and starless nights, in their (possessive, belonging to) translucent skin and ghostly gauze dress.
