Here are the special rules for Monster Hunts.
Amulet of Life - Every character and side kick is given an amulet of life. This amulet teleports them back to the City of Tele'ron with 1 HP. when they fail their 3rd saving throw. Pets, mounts, and familiars do not get this amulet. At the end of the monster hunt, success or failure all amulets are taken back by the empire. If the player leaves the area using any magic or reason the necklace teleports back to the empire. (There is no way mechanically the player can keep the amulet, it is always taken back)
Pet Dismissal - A player may send their pet, mount, or familiar home at any time. (even in the middle of an attack roll) If they do, they may not bring them back for the rest of the monster hunt. This rule does not apply to sidekicks as they have Amulets of Life.
