Is Acid an Effective Way to Pick a Lock?


Advice


If you apply acid to a locked door, does the door effectively become unlocked? Does it matter what quality the lock is? Does acid splash make you a lockpicker?


See this thread.


As nonsensical as it is that pouring acid into a lock would do nothing while pouring a like amount of acid onto the average person could kill them, that is how it works.

Acid somehow does not bypass object hardness, so you're probably better off just making a Strength roll to break the lock.

It's not nonsensical at all. Acid cannot burn through just anything at the same pace. An acid that can cause severe third degree or worse burns on a human might do little to a piece of steel. Acid does however have the benefit of not being reduced vs objects like other types of "energy" attack mechanics (I and the designers are aware that acid is not energy but it is grouped as such due to similar game mechanics), which means that the amount of acid damage vs the amount of say fire, cold, or electricity damage that you need to damage an object is much, much less.

That being said...

No it doesn't, but an adamantine dagger or arrowhead is a good start. Adamantine ignores an object's hardness if it is less than 20. Most locks are made out of iron/steel and have a hardness of 10. Magically reinforced (see Environment, Walls) can make them harder, but in general a small adamantine blade can cut a lock off a door (or cut the door off the lock) in short order.


Near the top of the list of things no veteran adventurer should be without: Adamantine Chisel.

Better than any lock pick.


Has anyone figured out what the cost for an item like an Adamantine chisel? I haven't been able to figure out the cost or find any sort of developer statement as to what items like these cost.

The problem is exactly that--the pace of corrosion matters for combat, but when you just pour acid into a lock, it shouldn't just do 1d6 once and then become inert or whatever.

I think the likelihood of a steel lock is extremely low. Even modern locks are mostly made of brass. Plus, etched steel exists, thus acid can damage steel.

I recognize that the original poster implied he was talking mostly about Acid Splash, but I was talking about acid in general--say, like a vial of acid, which would not magically evaporate or anything as the spell's acid does.

That's nice to hear, but I don't recall ever seeing that. I actually do believe you on this, but would still humbly request a citation if you don't mind.

If the goal is to bypass Hardness, then it should cost like a weapon, which is to say +3000gp. What a chisel costs in the first place, I couldn't tell you, but it's certainly pocket change compared to the 3k Adamantine bits.


Pathfinder changed that aspect of the acid energy type. It now is affected just as much by hardness as other energy types. A GM is allowed to --- allowed is a bad word but my backspace is broken -- make exceptions, of course.

The citation is Additional rules chapter, Smashigng Objetcts.

Damn backspace.

Thats been removed in Pathfinder, along with sonic damage not being reduced. All energy types are now halved before applying hardness. And cold damage is no longer reduced to 1/4th, its at half like all other energy types.

However, it does say:

Quote:
Some energy types might be particularly effective against certain objects, subject to GM discretion. For example, fire might do full damage against parchment, cloth, and other objects that burn easily. Sonic might do full damage against glass and crystal objects.

and:

Quote:
Vulnerability to Certain Attacks: Certain attacks are especially successful against some objects. In such cases, attacks deal double their normal damage and may ignore the object's hardness.

So an acid specifically designed to eat through metal could ignore it hardness, and do 2d6 damage. But that is entirely up to the GM.

Well...that certainly puts it out of range of being rather useful as such an item. Might as well just throw it on a weapon and call it a day.

Just put it on an arrow. Arrows are priced in batches of 50. So a single adamantine arrow is 60gp. An arrow used in melee is an improvised dagger.

Isn't ammo destroyed when used. Would you have to use a new arrow for every lock?


For those keeping track of the Saga of Cheapy's Broken Backspace Key, it's fixed now.

Adamantine Durable Arrow. Use forever.

Only 61gp.


Huh, that's weird. In one of the books for an earlier edition of D&D it specifically mentioned that strong acid is a good way to get past a lock you can't lock-pick. I wonder why that was changed?

Tool, thieves, masterwork.
