The party is asking me to reprise a character I've played before, due to the party build and theme that are going on. He's been a cavalier, a paladin, and a multiclass of the two. Key point being- the horse is an integral part of the character(if I run him paladin, he'll be taking Boon Companion at level 5 when the mount shows up).
Other than the heat issues, is it a stupid idea to bring a horse to this AP? Will there be a lot of underground areas, etc? For example, I know if I had a mount in RotRL he'd be just about worthless, between the haunted house, the clock towers, and all the underground areas.
Should I lean toward the cavalier version, or the paladin version? Party comp so far is looking like Inquisitor of Sarenrae, Cleric of Sarenrae or Oracle, and a Wishcrafter Sorcerer.
