Legend
It did make a difference in how we viewed the mount, though. I recall a 3e game in which I played a half-orc paladin called Grudnuk whose steed was a dire weasel named Fluffles. When the party was captured by a large hunting party from an orc tribe, the only way he could dissuade them from killing his mount was to swear on his honour as a paladin that he would make no attempt to escape as they were transported back to the tribe's stronghold.While I appreciate it may not have worked out very well in 5e, I kind of miss the good old days of living steeds and familiars. If it dies, it's dead, and you have to find a new one (which was either impossible or very difficult for paladins).
Nah, who am I kidding. Nostalgia is great, but permanent companion death rarely if ever contributed to my fun even back then.
When the hunting party stopped to rest that night, the escape was on. Fluffles, without any prompting from Grudnuk, wriggled loose from his bonds and nibbled the ropes from the captured party members. While a diversion was created on the edge of camp, Grudnuk helped his companions aboard his steed - and ordered Fluffles to run off into the night. Then he went back and sat down in the centre of the camp, and waited for the orcs to come back.
Sure, it left the party split, and led to the rest of them having to sneak back in the next night and rescue Grudnuk without waking him up, but it was a cool bit of tension that resulted from the mount being mortal.
