I have a swift and deadly hunter variant druid, who gains “Bonus to Armor Class when unarmored (as monk, including Wisdom bonus to AC).”
He rides his animal companion as a mount. I was wondering if there was any feat, or other option, that would allow him to share that AC bonus with his mount. The only option for this that I can find is the sohei monk, but that requires four levels in an otherwise-useless-to-me class, and also does a lot more than I require. A feat would be ideal, but a dip of fewer and/or better levels (ideally both), a spell (ideally a low-level, long-lasting druid one), magic item (ideally cheap), or whatever else will be considered. The benefit must not require actions in combat, however, and cannot be limited in the number of hits it will cover in a given round (because Mounted Combat would be far better in that case).
Official D&D 3.5e products, licensed D&D 3.5e products, official Pathfinder products, and Dreamscarred Press 3.5e or Pathfinder products are preferred, but third-party 3.5e products and other third-party Pathfinder products will be considered.
Options for allowing his mount to add her own Wisdom modifier to AC would not be particularly helpful; her Wisdom is 10 less than his. So no just buying her a monk’s belt and being done with it.
