If you die you don't lose your things you just lose the ores you've mined out of Charm Furnace (That is what I termed it doesn't have to be title that lol) and you awake at the puppy snare with (if you left your puppy with the Pet shop owner) your dog slobbering on your face (if you didn't leave your dog with the Pet shop owner) some arbitrary dog pulling at your leg with OSRS gold sharp teeth.
Other player can strike you in some specific areas in the Charm Furnace whenever they another dragon-rock fall kills you they can take Charm ores you drop and if you are carrying any at the time the charms its self.... Anything you gain in the cavern could be dropped (apart from things from arbitrary events) but everything you earn can't be lost from the Mini Game.
You cannot bring a dog, cat, monkey or a familiar or recognizable pouch to the cavern the pressure from the other dimension is too much for their essence. The reason you cant bring a dog, cat, monkey down there is because they can get hurt to easily, the lizards that aren't dragons may evade falling stones and hide readily upon your person away from the creatures, and the dragons, well nothing really can damage that Runescape gold 2107 monster.... The birds can fly away from the rocks and creatures without any problem...please note that in case you bring the pets that are allowed you cannot lose them through passing in the Mini Game.
