Using earth glide is very similar to an incorporal creature moving within an object. And this has clear rules in the core rulebook I would use that as a reference.

"An incorporeal creature can enter or pass through solid objects, but must remain adjacent to the object's exterior, and so cannot pass entirely through an object whose space is larger than its own. It can sense the presence of creatures or objects within a square adjacent to its current location, but enemies have total concealment (50% miss chance) from an incorporeal creature that is inside an object. In order to see beyond the object it is in and attack normally, the incorporeal creature must emerge. An incorporeal creature inside an object has total cover, but when it attacks a creature outside the object it only has cover, so a creature outside with a readied action could strike at it as it attacks."

According to this, a creature with earth glide and tremorsense hiding in the ground below his enemy, has total cover, and can emerge for a moment when attacking, having only cover at that moment. Thus can be attacked only with a readied action, and at AC+4 (because of the cover). Broken, but true.

Of course if under the ground in total cover, the creature does not see who is standing above it (if someone newly moved into the range of the tremorsense). So it must emerge to identify if it is ally or enemy. But I do not see this as a hindrance.

Earth Elementals (as creatures having the Earth subtype) all have tremorsense. See decr. of subtypes.

I vote for this last option, written by FarmerBob. That seems the most logical for me.

The core rulebook will definitely need an errata for poisons. Until that time we can only house rule it and continue endless debates. I would welcome an offical posting from a lead designer here in these topics. I think all of us would do.

As part of this house ruling of the unclarified rules, I would also recommend using one option mentioned earlier in one of the poison topics:

Secondary saves (all saves vs damage, thus excluding the initial save) should be made at the beginning of the poisoned creature's turn.

Why I say this:
- If secondary saves all occur during the attacker's round, what happens if the attacker dies before the duration of the poison elapses? Do you have to memorize it's initiative count to know when the poison hits again? It would be much more convenient to have the secondary saves in poisoned creature's turn.
- It is not exatly written in the core rule book, when the secondary saves have to be made. Yes I know, after the oneset time has elapsed, but that's not the _exact_ definition I would expect. Because in case of poisons with 0 oneset time, the secondary save could be in the same round as the initial save, but during the poisoned creature's turn (if it's initiative was later or in the next round if it's initiative was earlier).

Question on the eidolon evolution: Slam (this does not seem clear to me according to the current text)

If I select Limbs (arms) + Slam, does that mean my eidolon has
a) 1 extra limb with 1 slam attack
b) 2 extra limbs, but one can be used for a slam attack, and the other for claw attack
c) 2 extra limbs, but only one can be used for a slam attack, and the other for non-attack purposes
d) 2 extra limbs, with 2 slam attacks

Question on a summoner:

How much maximum HP does the eidolon have at the time of summoning?
- Is it an average? (as usual in cas of summoned monsters, e.g. 11 hp for 2 HD, 2d10)
- Is it the maximum? (e.g. 20 for 2 HD)
- Is it randomly determinated at each summoning?
- Is it determined the same way as for PCs? (rolled separatly for each HD, and keeping track of rolled values, and is the same at each summoning)

I found the following text not clear. I think it needs some corretion:

"A summoner can summon his eidolon once per day in a ritual that takes 1 minute to perform. When summoned in this way, the eidolon is always at its full hit points. The eidolon remains until dismissed by the summoner (a standard action). If the eidolon is sent back to its home plane due to damage, it cannot be summoned again until the following day."

- Not clear, if the eidolon is dismissed by the summoner, can it be summoned again on the same day?
- If it cannot be summoned again on the same day afer a dismissal, why does the text say that it can be only summoned next day if slained due to damage? (If it is only summonable once per day, this sentence ha no meaning.)
- Why does the text say that "When summoned in this way"? Is there another way?
- According to this sentence: "When summoned in this way, the eidolon is always at its full hit points", I would assume that it can be summoned after dismissed, however if on the same day, it has the hit points it had last time when disappeared.
