Here's a brief table explaining how different systems say to handle Specialty rerolls.

"Recursive" means that if you get a 10 on the result of a Specialty reroll, you roll it again; if you get another 10, then you reroll that as well, and so forth. If this is "no", then you only get to reroll once, regardless of whether you get a 10 on the reroll or not.

"1s count" means that 1s on a Specialty reroll subtract successes
as normal. If this is "no", then 1s on a Specialty reroll do **not**
subtract from your total successes.
