Would you consider soothsaying (whether using atarotharrow deck, reading the winds/predicting the weather, etc. etc. etc) be a performance or a profession skill?
Or neither?
EDIT: Also, possible minor alteration, but would you allow the Decataur'sability be able to be applied to oracle spells instead?Spoiler: Nature MagicNature Magic (Su): Decataur are finely tuned to the druidic and shamanistic ways of nature. they increase their caster level for all druid and ranger spells by 1.
