I have no idea what the designer who did the EE was thinking. But the way I'd interprate it is as follows:
1A: EE has NO miss chance against things in contact with the ground. It moves through and senses through earth/stone as easily as a human moves/sees through air. And sorry: I don't think refraction of light is similar to tremor sense; which I assume picks up on echoes through the ground. You could if like make it a mystic sense rather than sonar-ish one to avoid any pseudo scientific arguments.
Thanks, Drunk.
The part about requiring a miss chance roll was based on the EE using its
darkvision 60' ability. If it has that ability (and I'm not sure it should), then it should be able to visually see creatures as well as sensing them via tremorsense. Would
darkvision work through solid stone? If it does, would the surface of the stone cause the image to blur, just like looking through the surface from underwater makes the image wavy?
I think I'm just going to get rid of the
darkvision ability altogether. With a good tremorsense -- which I think the EE has -- there's really no need for it. My players argument was that even if the EE could pinpoint them via tremorsense, it would still be attacking blind and the 50% miss chance would apply. They equated it to being able to pinpoint a creature who is invisible. But I think I'm going to treat it more like a bat which uses echolocation -- they don't have a 50% miss chance (presumably because their mode of sight is normal for them) so the EE shouldn't have the miss chance either.
1B: You could handle it a few ways. You seem to be thinking that it should be harder to hit than normal. I'd agree with that. I'd give it it's usual AC and then give it cover. About 75% to 90% with the appropriate miss-chance.
Your numbers sound like 2E numbers.

Nothing wrong with that, but I'll convert to 3.5E numbers and figure an AC bonus of +4 to +8 depending on the amount of cover.
2: Now the levitating or flying PC is much harder for the EE to deal with. If the PC only occasionally touches the ground then the EE only occasionally knows where they are. If the EE can guess the likely course of the PC and readies and action (and these are judge calls based on variables in the scenario) I'd allow it to take a swing but give the PC 90% concealment and the miss chance for it.
Remember that all of these actions are taking place simultaneously -- initiative is just to keep things orderly for game purposes.
In that case, they are touching the ground at the same time that the EE is taking its action, so there shouldn't be any issue with a delay. Well, unless they move one round and don't the next.
But I think I've talked myself into not allowing a levitating creature to touch the ground at all. If they attempt to stretch an appendage to the ground, the spell simply lifts them higher by the same amount... I'll have to start another thread for this, though.
3A: It works the other way around for the PCs. How do they know where the EE is going to poke itself out of the ground? If they can make a reasonable guess (and be fair here, try to decide where it will be before the PCs make their intentions known) let them take a shot. If the PC's do get a shot in then, as per 1B give it cover and the miss chance.
Well, for readying a spell the caster doesn't need to know where the creature will appear. It's perfectly valid to say, "I ready an action to cast
scorching ray at the EE as soon as I see it." If an appendage appears from out of the wall and attacks someone, then as a continuation of the swing returns back into the wall, does the readied action happen? If so, what is the effective AC that the spell needs to hit?
Or is attacking an appendage the same as a called shot and called shots don't exist in 3.5E, so the readied action never happens?
3B: Judges call. I'd say no, but then I'm generally considered a pretty harsh.
I think I'm going to have to stick with my original ruling on this one. I've been thinking about it and if the acid/oil were left behind when the EE retreated into the rock, then spells like
glitterdust wouldn't work either. And I'm not prepared to rule that the ability to move through rock is quite
that powerful.
Yes, this has been great. Thank you!
I only wish I could turn back the clock and play that encounter again.

I'll just have to make sure that they face more EEs and I'll play it right when that happens.

Given that the module is RttToEE, that shouldn't be too hard!
