@Vander_NarsFind Steed – is the intent to allow DM to pick a better steed for paladin as he lvls up or stuck with 19hp warhorse at lvl 20 it's really meant to be a mount rather than something that fights, but I'd allow other forms that fit the paladin's need

@Vander_Nars For instance, a paladin shipwrecked on an island could summon an aquatic mount – DM's choice, based on deity's intent
