The Hobbit movies had dwarf cavalry riding goats, which I found to be a good fit despite the films' shortcomings - they dwell in mountains, and, like dwarves, are known for their beards.
Dwarves cavalry conjures up echoes of bikers. Bikers in leather & metal, riding iron hogs.
D&D traditionally considers horses un-suitable for underground adventuring (though mules are OK according to D&D tradition, so if you want a somewhat comedic cavalry).some kind of Calvary mount for dwarves. I've considered horses, boars, and even bears A mount that would function well underground is preferable... I am open to homebrewed ideas!
Yes, but in a fun way. Maybe they could have a lesser 'tame' version, perhaps with an enlarged dorsal plate that shields the rider when tunneling?Also, I've considered bulettes as a possibility, would that be to OP?
