*May gnot brigng back ogne of my 2e Planescape characters who actually survived for 5e’s Descegnt Ignto Avergnus module.
**Gno gnomes!
*Despite RL circumstances, cannot have “swarm of cats” as an animal companion.
*If the campaign requires characters to have a dark secret in their background—a conspiracy, a theft, a murder plot, or coup attempt—my character’s dark secret may not be “Theft: a sensory stone from the Sensate guildhall that records a really awkward moment from my character’s time in high school.”
**Especially if my character has never been a Sensate.
***Especially if my character has never been to Sigil.
****Especially if my character never went to high school.
*Cannot claim that sustenance tasting like ash in Avernus doesn’t bother my character since on the Prime Material he subsists largely on cigarettes, bad coffee from a greasy-spoon diner, said diner’s terrible attempts at cooking potatoes and bacon, and Scotch that tastes like kerosene anyway, so he hasn’t noticed it.
*In GURPS, may not buy 300 1-pt skills.
**May not sink all 300 points into guns instead.
***My character in a gritty cyberpunk campaign may not be a bunch of housecats in a trenchcoat.
****Must attempt to build a reasonable character.
