There is a Smithing Stone, which is 3 and elden ring weapons an inscription on the ground suggesting that you should be looking down. You will see a series of platforms that you could fall on, so follow them until the bottom where you will discover a tower that is accessible and the Golden Rune [5]. Pass through the tower to get to a balcony overlooking a deep pit. You can grab your Rainbow Stone x5, then go forward and up the steps until you can reach the door that leads right back into the Spot of Grace.
Once that shortcut is unlocked, the time has come to dive into that pit. Return to the spot that you stumbled upon the rainbow stone and you will notice an umbrella that you can use for access to the platform that is on to the side that is on the other side of room. Go across the platform and then into the tunnel to discover an Arteria Leaf, and a bat waiting to be ambushed. Return to the tunnel, where two bats wait. They can be defeated similar to how you handle the stormhawks. Guard counters are always successful! Use nearby rafters for means of a bridge to access an item that is on the opposite side, which is a Smithing Stone [2].
Continue carefully dropping down until you are at the bottom of the room which is where you'll find an Golden Rune [2]. Begin walking down the path Be careful not to be overwhelmed by the rats that are creeping around, including one powerful Large Rat who can drop a Rune Arc. To the left is Poisonbloom which is x3 and on the opposite edge of the wall there's a Scarab that you could kill to buy Elden Ring Runes use the ability Rancorcall.
