Diaboli Tail Code
Many diaboli also learn to communicate simple ideas by twirling and positioning their tails in a sort of elaborate code. The purely visual diaboli tail code can convey even complicated concepts, but it takes roughly twice as long to express something in the diaboli tail code as in any spoken language. Any creature that can see a diabolus using the diaboli tail code may make a DC 10 Intelligence check to realize the diabolus is attempting to communicate. Any creature may learn diaboli tail code, although only creatures with tails of their own can "speak" it.
