Bag of Runes

This purple cloth bag has a bright white dwarven letter that changes over the course of a minute. Inside the bag there are a collection of 11 slightly shiny, oddly shaped rocks.

When a creature attempts to take out  one of the runes of the bag they roll 1d12 to determine which rune they take out.
Each creature can only use it once per long rest.
The runes last for 48 hours after they have been taken out, after that they become normal rocks.
After the effect is done, the rune breaks.

-1 or 12: A blank rune, if attempted to identify trough non magical means, the rune breaks and a rotting odor comes out of the rune, keeping the 5ft. area that the creature is standing on, smelling for 1 minute. If identified trough magical means, you may reroll the number and take it, unless its another 1 or 12
-2: A rune of halagaz, when taken out it whispers to the creature "Nothing will stand between me and the path", if you press it against a rock, wood, or cloth materials it causes it to disintegrate any of that material in a 5ft. cube.
-3: A rune of jera, when taken out it whispers to the creature "May wealth find its way to you", if you put it near a copper, silver, electrum or gold piece, it will generate 1d8 more coins of the same value.
-4: A rune of ehwaz, when taken out it whispers to the creature "Tell me your destination, and I'll guide you", if you mention a place you have visited before, the rune will inform you of the state of the location, as well as any traffic or events that happened on the fastest road to the location.
-5: A rune of dagaz, when taken out it whispers to the creature "You shall be untouchable under my wing", it lets you cast remove curse or shield as long as you keep it on touch with your bare skin.
-6:  A rune of ansuz, when taken out it whispers to the creature "I shall show you the stars", it lets you cast see invisibility or darkvision as long as you keep it on touch with your bare skin.
-7: A rune of perthro, when taken out it whispers to the creature "The law of equivalence is all to me", it lets you cast polymorph on yourself.
-8: A rune of berkano, when taken out it whispers to the creature "May your allies be everlasting", it lets you cast mirror image on yourself and another creature you can touch.
-9: A rune of algiz, when taken out it whispers to the creature "None shall harm thee", it lets you cast mage armor on yourself as long as you keep it on touch with your bare skin.
-10: A black rune, when taken out it whispers to the creature "Let the void consume their bodies", if you throw it as an attack, the target needs to make a CON save DC equal to your spellcasting DC, on a failed save, the target gets hurt for 2d8 necrotic damage, or take half as much on a successful save.
-11:  A rune shard, when taken out it whispers to everyone except the creature that took it out, in a 30ft. radius "I am sorry Isaac" and duplicates the previous rune effect instantly on the creature.
