      It removes one Durability per second for a total of 8 Durability lost. Almost every item in the game has minimum 300 Durability...unless someone is running all Crystal gear its use is questionable.

          Is two casts powerful enough to break something or do I need to go on ng+ and get another acid surge for it to actually break something?

            honestly its the only thing people will avoid like the plague nobody wants their items broken so it can be used to cut off areas from either attacking phantoms or fleeing hosts and to stand in to get away from attacks but the casting time is slow but for what it is not bad it can be useful but thats just because people dont know what it does, dark souls just kind of trains you to not ***** with brown goo because itll end badly with crusty clothes and weapons but to be honest worse case scenario if you stand in it the whole time like you were trying to break your stuff / are afk it only does 8 damage to durability per cast so unless they run through the game to get to ng +7 and have a ***** ton of castings of this and are just trying to break peoples***** then its low key pretty useless and wont do much if its just 1 or 2 casts but nobody knows that. I understand why its garbage like they dont want people to be able to invade and just break everyone's***** super duper easily but it makes it*****ty for the pvp when it does 1 durability damage per second and thats just if someones actively in it like people dont know its actually garbage so they avoid it so it works good but it is real bad and basically just for trolls and area denial for people who are ignorant to how bad it really is but id say its better than toxic mist for that exact reason and theres double the casts, maybe not as good as poison mist depending on what youre trying to do but mostly in pvp this will be better than every mist pyromancy there is
