The Resistance Table

In Call of Cthulhu, there was a mechanic called the Resistance Roll, to be used when two characteristics were pitted against each other. It could represent shoving someone out of the way, STR vs SIZ, or an Investigator dying from poison, CON vs POT (the potency of the poison). A simple but clunky formula gave you the chance of success given the characteristics, but there was also a table that had the math already done for you for characteristics from 1 to 31 against characteristics also 1 through 31. The seventh edition of CoC did away with this mechanic, as did Delta Green, which replaced it with the opposed roll. So why do we care about this defunct mechanic? Lots of folks like to use CoC content in their DG games (including old DG content published for CoC) and the Resistance Roll is a tricky mechanic to convert. This post seeks to compare it to DG's opposed rolls and offer some conversion advice.

ANGUISHEDWIRES session one

Two years ago, I played in a dungeon crawl. It was pretty fun, despite us basically dying horribly every session. I asked my friend mellonbread for the dungeon's music tracks, printed off the floor maps, and hopped into the discord call. Our three musketeers were:

Márta Benedek, a devout Muslim from the ever-swelling ranks of the Benedek family (a female dominated clan who turns its daughters loose on the world as adventurers).

Octavia, an educated woman, both an alchemist and an arcanist.

K'rizzt Tri'Orgen, a "connoisseur" of dark elf culture so obsessed that he'd dyed and painted his skin to look just like them.
