My paladin just hit level 5, and in addition to endless Zone of Truth callbacks and learning the heartbreaking truth about Moonbeam, I'm pumped about summoning my first mount. My character is a tank and very devoted to protecting his three caster friends, including the Protection fighting style.
This makes me think that rather than being up on a high horse, I'd like a mount that's agile and relatively low to the ground, to improve my ability to tackle enemies and throw myself in front of friends. I'd also trade this off for other traits that make the mount especially good for protection. Are there any plausible mounts that are good at this?
My DM will accept nonstandard and uncommon mount animals, as long as they're not plainly OP (no flying, firebreathing, etc).
