Green Slime vs Undead

[Kethrian]

So, considering that green slime devours flesh, wood, and metal, would it be a safe extrapolation of the rules to say that it deals 1d6 con damage per round to anything which isn't immune to con damage, and 2d6 damage per round to everything else that it eats, such as undead/clothing/etc.?

[ariasderros]

That's how I have always handled it.

Not a safe extrapolation of the rules, just an attempt to justify flavor text.  If you're in a position to make this ruling, you're the DM, and should probably not be thinking about how you can make up something to hurt the undead with green slime.  Instead, you might consider how much more interesting and menacing an undead creature can become, if it's thoroughly infested with the stuff... suffering no harm for it, but serving as a vehicle to carry it around.

You might also consider the confusion potential of undead suffering cosmetic damage only.  Suppose a meaty undead like a blaspheme, advanced wight, or mummy lord, misidentifies at a glance as a simple skeleton, because all its soft tissue has been stripped away by the slime.  How will enemies react to it?  What's likely to happen to them if they do?

[Kethrian]

Ah, but with spells like Slime Hurl and Slime Wave, it's good to know how ineffectual it will be against undead opponents.  Is it completely useless because they're totally immune, or will it just slowly damage them, allowing you to possibly flee and come back later when the deadites have been totally consumed?

Here's another related question: How do Undead affect Green Slime? Can a green slime get mummyrot or be level drained or what have you?

Considering green slime is listed as a trap-like encounter and not a creature, I doubt it.

[ariasderros]

How does level drain affect black mold? It doesn't. How does Mummy rot affect yellow mold? It doesn't.

Moving on.

The reason I've always handled Green Slime as damaging Undead is because the stuff is highly corrosive. It behaves like an acid. Acid immunity doesn't protect against it because, while it behaves like an acid, it isn't acid. It is a living substance that is attempting to break down the material that it rests upon, regardless of what that material is.

And it can't fail to do what it's attempting to do?  Nor can it succeed, but its success be irrelevant to something that's immune precisely because it doesn't need what's being corroded to function?

Do you extend this immunity-breaking ability to everything that some creatures just flatly ignore?

I'm trying to decide if I  should read that as being slightly irate. If so, #1.
If you are asking for further justification on why I handle it this way out of curiosity, then #2.

#1)  I was stating how I handle it because someone else asked, that is all. Do not attack me for my opinion. If you have a RAW argument for why I am wrong, say so. If you just don't like my RAI or my opinion: so what?; why do you care to belittle my opinion just because yours' differs?

#2)
A) RAW, green slime isn't acid, so it is not genuinely "breaking" any immunity.
B) RAW, there is nothing that would make undead immune to it eating their flesh and bone, other than the fact that they are immune to the Con damage. That isn't fluff, that is an explanation of how the rules are taking place in the game world. (i.e. the rogue is hitting a vital spot to SA is verisimilitude text, the fact that they are "not equal to members of many other classes in combat" is fluff, and the explanation of how SA works is crunch)

Thus, it is my belief that Green Slime is meant to deal damage to undead (and constructs) under RAI, and was only not elaborated on because it would have been more ink on something that was, at the time, mostly irrelevant.

And the only reason I allow for this "immunity-breaking" when I am the DM is because of how I view the RAI of this one particular "substance". Otherwise, even things that legitimately break immunities are something I raise an eyebrow for. I only just barely can tolerate the existence of Grave Strike because it prevents an entire class from becoming irrelevant, but I hate Spark of Life.

Given the description, it would make sense for corporeal undead, which are made of magically animated organic material, to be corroded as well, as if they were made of wood.
