R6 (Variant of R5, “Censer”)
n/a || Bladder
Misinterpreted, not a variant. Miscategorized.
Magical Uses, Meanings, Pairings: Symbolically, pigs were seen as the foulest of the foul and generally unclean. This symbol, actually a pig's bladder, was used in curses purported to banish ancient Egyptians to a lower caste were they to pilfer tombs.
Anecdotes/Comments: It is unknown whether or not this actually has any effect, as most societies with avid curse-breaker programs do not have caste systems. Some speculate that if not dissipated, it will cause others to look upon the affected with distaste or to be disbelieved and disliked, but no conclusive proof can be found.

R10 (Combination of R8, T28 and N29, “Flag”, “Butcher’s block”, and “Sandy slope”)

Anecdotes/Comments: This was actually a fun one to test when it was used in conjunction with P5. Or, well, it was fun once Archie suggested bringing brooms and earplugs. Before that, we always assumed it did the same thing as R13.
