Location Of Rotten Breath

The Location Of The Cathedral Of Dragon Communion

Like other Dragon spells in the game, Rotten Breath can only be purchased from a specific dragon church in the game. And in this case, you’ll have to travel to the Cathedral of Dragon Communion, which is located in Caelid. It can be accessed very early in the game if you know the path.

Purchasing Rotten Breath From The Cathedral Of Dragon Communion

The Cathedral is located near the great bridge leading to Caelid’s legacy dungeon, the Redmane Caste. Just go to the location shown on the map, and you should arrive at the Cathedral. At the Cathedral, interact with the altar so that you can purchase the Rotten Breath.

Flying Dragon Agheel In Limgrave

Make sure that you have at least 1 Dragon Heart before going to the Cathedral. You will need that to purchase the Rotten Breath incantation in the game. If you don’t have a dragon heart, then you’ll have to fight and kill a dragon in order to obtain one. The easiest way of getting the dragon’s heart is to fight Agheel in Limgrave, as he is the easiest dragon that you can quickly kill.

The Best Rotten Breath Build

The Best Rotten Breath Build
  • Weapon: Antspur Rapier (Poison Infusion)
  • Sacred Seal: Dragon Communion Seal
  • Talismans: Crimson Amber Medallion +1, Rotten Winged Sword Insignia, Dragncrest Greatshield Talisman, Erdtree’s Favor +2
  • Incantations: Rotten Breath, Ekzykes’s Decay, Scarlet Aeonia
  • Wondrous Physick Mixture: Greenburst Crystal Tear and Hidden Cerulean Tear

This is probably the best build that utilizes the Rotten Breath to its fullest potential and lets you play around with other weapons that also cause rot. Make sure to level up your Vigor and Arcane primarily, as you’ll need them the most for your Rot Build. Then you should focus on the Faith stat if you want to utilize other scarlet rot incantations in the game. 


Antspur Rapier is the best weapon that you can choose for a rot build. Make sure to infuse this weapon with Poison. That will not only make the weapon deadlier, but it will also scale with Arcane. You will proc alongside scarlet rot as well, and the weapon will scale off Arcane, which is the primary stat of the build. 

Sacred Seal

Dragon Communion Seal is the best seal that you can use to cast dragon incantations, including the Rotten Breath. It basically boosts all types of dragon incantations, and it additionally scales off Arcane. This is extremely useful as both weapons and the seal scale off the same stat. Both of these will be used to inflict scarlet rot on your enemies additionally.


Prioritize Vigor and Arcane for the rot build. I suggest you to use the Crimson Amber Medallion +1 to boost maximum health, ensuring prolonged survival as scarlet rot affects enemies. The Rotten Winged Sword Insignia increases the damage output of the weapon with successive attacks. That is very useful for a fast weapon like the Antspur Rapier, which deals low base damage but is fast, and you’ll be able to hit the boss quite a few times before having to dodge. 

Dragoncrest Greatshield Talisman is going to increase the amount of physical damage that you can take in the game. This will allow you to stay alive for longer in battle until scarlet rot finishes the enemy. Lastly, Erdtree’s Favor +2 will increase your health, stamina, and equip load


The main incantation of my build is definitely going to be Rotten Breath. However, if you want to add variety to your rot build, then you can use other scarlet rot-inflicting incantations. These include Scarlet Aeonia and Ekzykes’s Decay. You should note that you’ll have to invest more in the Faith stat in order to use some of these higher-level rot incantations. But you won’t need to use them, as Rotten Breath is already very strong in the game.

Wondrous Physick Mixture

The Hidden Cerulean Tear will negate all FP consumption for a limited amount of time. You can use that to launch a Rotten Breath as soon as you enter a boss battle to get the upper hand by inflicting scarlet rot on the boss. And the best part is that no FP will be consumed for that first Rotten Breath.

The Greenburst Crystal Tear boosts your stamina recovery speed. You’ll need that as the Rotten Breath heavily drains your stamina after a single use, so it will come in handy to have better stamina recovery speed. It just makes your fights safer and comes in clutch when you least expect it. 


Elden Ring has a lot of other great sorceries and incantations aside from the Rotten Breath. There is so much that you can explore and create in the game. And the variety is amazing, from boss design to making builds. The game lets you create bizarre builds like StrengthDexterityMageFaith, SamuraiBleedPoison, and Assassin Build.

There are so many unique and well-designed bosses that you can fight and test out your builds on. Some of these bosses will prove to be a huge challenge, like Malenia, while others will be extremely easy to tackle, like the Regal Ancestor Spirit.
