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 currently worn by the enemy. The enemy has to be in the mist. Acid Surge will deal approximately 8 damage to equipment durability of the victim stays in the cloud for the whole duration. If the cloud passes through the victim instead, they'll take about 2 durability damage
  • Not recommended for Arena-based PvP, but might prove useful in group fights as to scramble or worry opponents.
  • Curiously, this spell will mark objects on the map with a small acid surge cloud when touching them. This may be the spell trying to break their durability, as the same cloud appears when used on players.

      The only use for this is teaching people the harsh lesson of why you should never AFK while online in a souls game.

        Every spell should be reliable sometimes atleast to make it balanced, but i swear this thing has been sent into the depths, never saw a single person using this in all the 2-3 months i was playing ds3

          Tested with a friend recently, this thing only deals 8 durability damage if they stand on it for the entire duration and 2 damage done from point blank, the numbers on this page are outdated.
          Seems like it's completely useless now, not even good for breaking katanas, just don't bother with it, most armors have around 300 durability, you will never break them.

            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.
