Fighting underground (earth gliding question)

[Adjoint]

Earth Glide is described as similar to swimming trough water. Would penalties for fighting underwater apply for underground fight (fighting inside the ground, not in a cave)?

Can a creature that is earthgliding use its spells and spell-like abilities against other creature that is earthgliding, or would the earth between block the line of effect?

Earth Glide description also suggest that the creature using it doesn't create any ripple or other sign of its presence. WCanit still be detectected with tremorsense, or would earth glide be to tremorsense like invisibility is to normal sight?

[Volkard Abendroth]

RAW does not specify any of this.

Earth glide allows movement through stone and dirt. It doesn't change anything else. It also is not described as a person swimming, it is describe as 'as easily as a fish swims through water.' It is a description of ease, not mechanics (for example, you don't need to make swim checks while earth gliding)

You still need line of effect and such to make attacks, it doesn't provide any protection against detection in and of itself (earth between you and something else does, in both directions.)

If it helps, on the last one walking on stone also doesn't create any sort of ripple, but is certainly detectable by tremor sense.

1) no. Undergroud target cannot breathe(but check description, many GMs handwaive this). In ground can not see beyond self with normal vision, lack of perception leads to whole host of issues.

2) normally line of effect is cut but some spells ignore that general clause. Lack of perception leads to targeting issues.

3) Tremorsense percieves earth gliding creatures as they are touching the ground.

Another issue is can you summon an earth creature while earth gliding (into an adjacent square)?

See meld into stone for more information.

If the form grants a swim or burrow speed, you maintain the ability to breathe if you are swimming or burrowing.

It you get a form with burrowing speed, included earthgliding, you are able to breathe while burrowing/earthgliding.
