Pyromancy of Carthus of the Sands. Emits an acid which corrodes weapons and armor.

Carthus' swordsmen attached great value to victory, and would not shun the use of such pyromancies. For where is the honor in death and scoured bones?


Acquired From




  • Destroys the durability of Weapons and Armor of the enemy. The enemy has to be in the mist. As of Version 1.08, Acid Surge will deal approximately 110 Durability damage if the opponent stays within the cloud for the entirety of its duration. When cast at point blank, it will deal approximately 20 Durability Damage.
  • Can be used around corners and through objects.
  • Often used as a "smoke screen" in pvp, to confuse your opponents, since its primary use is kind of limited.
  • Not recommended for Arena-based PvP, but might prove useful in group fights as to scramble or worry opponents.

      Well, if you have a free attunement slot from your starting class, you can keep this on hand to troll the rare AFK host you might invade. How sadistic you'd have to be for that, I don't know.

          I think this spell would be much better if it was able to hurled like a ball of acid and explodes into a puddle at the end. Like an instant 50 durability damage upon direct impact and 5 durability a second for the puddle.

            Tried this on an afk player once - depleted all my fp, nothing happened. This is literally completely useless (I know it can be used as smokescreen, but so can poison toxic mist, and they actually also do what they're intended and cost same or less fp)

              I decided to test this against some Lothric Lads to see if it has any use in PvE. I hit a Lothric Knight for 312 damage, then used Hidden Body to allow me to cast Acid Surge on him 12 times, each for its full duration, while he stood there like a lemon. I then hit him again for 312 damage. I went down the stairs to the shield/spear hollows and repeated the test. I hit one for 174 damage to the shield and 387 to the body. I Acid Surged him as before, then hit his on the shield and body for 174 and 387 damage respectively. This implies that enemies may not actually use equipment, their weapons and armour may just be visual; defenses and resistances may be innate properties of each enemy.

                They really should max this out 2 seconds in the cloud it does lots of equip DAM
                but it costs all stamina and skill points giving the enemy a free attack
                That would actually make it useful and not pointless

                  Just so that this spell has any use, it would be neat if it dealt high damage to Dragonslayer Armor. You know, since it is equipment?

                    When this spell was disintegrating durability like it was nobody's biz it kinda gave an actual purpose for the Repair Equipment option for Andre.

                        I was under the impression that the spell slightly increased physical damage against enemies in PvE, is that not the case?

                          had this used on my by an invader for the first time yesterday. instantly broke everything I was carrying; straight swords, shield, bow, talisman... all instantly broken. repair powder didn't work.

                            Thanks From. Instead of buffing durability enhancing equipment, like the wood grain ring, you would rather nerf a spell that honestly needed a buff. Sure it was powerful, but it made the spell viable and required players facing it to rethink their strategy. It also provided casters a sufficient smoke screen to create distance between them and pressuring melee builds.

                            Sadly, the Acid Surge is useless once again. A single repair powder will render the fp investment to damage a weapon/shield mute. I think this is a prime example of a player community having too much of an effect on what dictates the meta. "Oh no, something is breaking my meta sellswords and carthus curved sword. From please nerf!" or "Oh no, my gank squads' weapons are breaking. God how can we gank with broken weapons? From please nerf." Seriously, why didn't from simply buff useless items instead of gimping a spell that needed a buff? Shame.

                              So. Know how the 1.08 patch Acid Surge way more effective than it was supposed to be by accident, and Fromsoft announced they'd be correcting that?

                              The 1.21 regulation change makes Acid Surge even weaker than it was before the 1.07 patch.

                                  Imminent patch to Acid Surge:


                                  Apparently, it wasn't supposed to be that powerful.
