I'm hoping some one can point out some rules I've missed, or some rules extrapolation I've overlooked that might explain some of these questions.

There are different descriptions for Earth Glide depending on what the source is. A quick search gives me 5 different versions of Earth Glide, with differences varying from subtle to major between them.

  • Earth Glide spell from the Advanced Races Guide for Svirfneblin
  • Deep Earth Sorcerer Bloodline in the APG
  • Rules for monsters with Earthglide; i.e. Earth Elementals
  • Earth Wizard School from the APG
  • The sort of nebulous description "you gain Earth Glide" from the Elemental Body spells

Can you run while Earth Gliding? The spell doesn't allow it, but it also only allows you to move 5 feet. Are, as the descriptions indicate, only some forms of Earth Gliding susceptible to the Move Earth spell stun? Are Earth Wizards the only ones at risk of shunting? What happens to a Sorcerer or a Wizard using the ARG spell when their duration ends?

Is it a movement type? Is it an extension of burrowing? It doesn't list a speed. Some descriptions start with "While burrowing..." but others don't. Does it, in those cases, use a creature's burrow speed? Does it ever confer a burrow speed? Which Earth Gliders can use it as a five foot step, and which can't?

Can you be partially Earth Gliding? Does this confer cover? Does it affect actions being performed? Can I attack a creature directly above me while completely submerged? Can I swing a weapon out of a hillside? Does it affect my swing, like trying to attack underwater? Would Freedom of Movement negate that penalty?

Some descriptions care about whether or not the earth is worked. What does worked really mean? Is a man-made pile of rocks worked? What if there are sizable gaps between rocks? Or even just rather tiny gaps? If I take those same rocks and orient them so they form a wall, with little to no gaps, is that worked? What if some one uses mortar? What if I smooth the stones so they fit very snugly? Say, like the walls of Machu Pichu? What if they are formed into into perfect cubes? Is compacted earth worked? How about baked clay, if we assume there is no straw or additives?

Do Earth Gliding creatures without Tremorsense have to worry about gliding down through the roof of a large cavern? Or unexpectedly emerging any other time? In general, how does a creature know what's going on around them while Earth Gliding?

Do I have to be moving to Earth Glide? What if I just want to put my head through to see the other side? Can I stick my hand in to hide a held object from sight? Can I submerge my feet to anchor myself from a Reverse Gravity spell? What if I'm not moving by choice? Can I Earth Glide to avoid being pushed into a wall? Can I glide into a wall while falling to gain control of my movement? Can I glide part of my body to slow my descent? What if I glide instead of hitting the bottom?

    \$\begingroup\$ That's a lot of questions you are asking at once, and I fear that it will be closed as unclear or too broad as it stands. I see your main problem with the ability is that there are multiple different things with the same name, that may or may not be the same ruleswise, as you say. These are valid questions, but you will need to distill them into multiple questions in order to make it fit the format of this site. \$\endgroup\$

    \$\begingroup\$ For this question, perhaps narrow it down to the first part: Are all of those "Earth Glides" the same and, if not, how are they different? You could ask some follow up questions as needed. \$\endgroup\$

There's nothing that special about the ability earth glide. Really. It's not the ability to become, like, totally intangible to earth or anything. At its core, it's just better burrowing. But I can sense your frustration; let me assuage it a bit by saying

The Various Earth Glide Abilities Aren't That Different

Perhaps it's helpful to see them in a list.

  1. The monstrous extraordinary ability earth glide reads

    When the creature burrows, it can pass through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water. If protected against fire damage, it can even glide through lava. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or other sign of its presence. A move earth spell cast on an area containing the burrowing creature flings it back 30 feet, stunning it for 1 round unless it succeeds on a DC 15 Fortitude save.

    There is no substantial difference between the earth elemental's extraordinary ability earth glide and the monstrous special ability earth glide.

  2. The description of the spell earth glide reads

    The target can pass through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water, traveling at a speed of 5 feet. If protected against fire damage, it can move through lava. This movement leaves behind no tunnel or hole, nor does it create any ripple or other sign of its presence. It requires as much concentration as walking, so the subject can attack or cast spells normally, but cannot charge or run. Casting move earth on an area containing the target flings the target back 30 feet, stunning it for 1 round (DC 15 Fort negates). This spell does not give the target the ability to breathe underground, so when passing through solid material, the creature must hold its breath.

  3. The deep earth sorcerous bloodline reads

    Earth Glide (Ex): At 15th level, you can glide through any sort of natural earth or stone as easily as a fish swims through water, with a burrow speed equal to half your normal speed. You do not leave a tunnel or trace of your passage. You can use this ability for 1 minute per sorcerer level each day. The duration need not be continuous, but it must be used in 1-minute increments.

  4. The odd one out is the earth wizard school which reads

    Earth Glide (Su): At 8th level, you gain the ability to move through earth, dirt, and stone for a number of rounds per day equal to your wizard level. You cannot move through worked earth or stone; only natural substances can be traversed. If your total duration expires before you exit the earth, you are flung back to the point where you entered the stone, take 4d6 points of damage, and are stunned for 1 round. Your burrowing does not leave a hole, nor does it give any sign of your presence (although you can be detected by creatures with tremorsense). These rounds do not need to be consecutive.


  • Without a burrow speed a creature can't use the ability earth glide. 1 assumes the creature has a burrow speed. 2 essentially grants the caster a 5 ft. burrow speed so that the creature can use the ability earth glide. 3's burrow speed is half its "normal" speed, a term subject to some debate but one on which the table should quickly reach consensus. 4 requires a house rule--it makes sense to base the creature's burrow speed on that of a creature with the deep earth sorcerer bloodline (i.e. half the creature's "normal" speed). (Unless, of course, the DM believes the creature who takes such a school should already have a burrow speed--a not unreasonable but nonetheless unusual expectation.)

  • The ability earth glide grants no additional senses nor the ability to survive while submerged. A creature who's using the ability earth glide gains no ability to navigate while doing so via the ability earth glide; the extraordinary ability tremorsense is recommended to do so. The DM may rule a creature without the ability to navigate is effectively blind when using the ability earth glide. Further, a creature who is using the ability earth glide risks suffocation; the ability earth glide grants no method of survival while using the ability.

  • Can a creature do X while using the ability earth glide? The answer to every question wondering about X requires asking another question: Could the creature do X while walking? If the answer is Yes, then the creature can do X while using the ability earth glide. If the answer is No, then the creature can't do X while using the ability earth glide. The ability earth glide modifies to the way the creature's burrow speed functions, which otherwise follows the rules of movement.

    Alternately, the question that may need asking is Could the creature do X while in his space yet surrounded on all sides by impassable barriers? While not moving, the creature isn't using the ability earth glide, and the ability earth glide has no effect.

  • For the creature how permeable is the material through which a creature can use the ability earth glide? This is unanswered by any of the ability's descriptions. Without further clarification, the DM must determine if the materials are equivalent to air, water, thick mud, or whatever. Also, the DM must determine--if he determines the material is thicker than air--what effect a spell like freedom of movement will have on the creature's capacity to employ the ability earth glide.

  • The sorcerer and wizard abilities earth glide only function through natural materials. The DM must define what's natural for the setting. This isn't weird, but it is arbitrary. It's part of a hoary tradition to allow DMs to say No to an ability that has the potential to be abused. Unnatural material might be walls of stone for one DM, while an unusual ore from the Elemental Plane of Earth would be another DM's unnatural stone.

Specific Questions

  • Can a creature be partially submerged while using the ability earth glide? Ask the DM. I'd say Yes and use the Aquatic Terrain rules for Attacking on Land.
  • Must a creature be moving to use the ability earth glide? Yes. When the creature stops moving, the creature's not burrowing and therefore the ability earth glide has no effect.
  • Does a creature with the ability earth glide threaten squares outside of the area into which he's submerged? No. the creature's not burrowing and therefore the ability earth glide has no effect.
  • Can a creature use the ability earth glide to avoid being pushed into a wall? Only if the creature can itself move some distance via its burrowing speed into the wall. As a reaction to being pushed? No.

Note that the rules for extraordinary ability burrow were omitted from the Pathfinder Core Rulebook.

  • \$\begingroup\$ In regards to the "Can I do [X] while using Earth Glide" section, I think it would be better to compare it to "can I do [X] while swimming" rather than walking due to the wording of how Earth Glide works, since it's "as easily as a fish swims through water". As to the permeability, I would say that terrain is as permeable as water in regards to the creature that has *Earth Glide" but not in regards to any spells it casts, or other (Sp), (Su), and (Ex) abilities it may have unless said spells or abilities specifically call out such an interaction. \$\endgroup\$ Commented Feb 17, 2020 at 21:53
  • \$\begingroup\$ Finally, Freedom of Movement would not have any interaction with a creatures ability to Earth Glide as how dense the material is doesn't matter, a creature can still move through it at the same rate regardless of if it's loose sand or solid basalt. \$\endgroup\$ Commented Feb 17, 2020 at 21:57
  • \$\begingroup\$ @RevenantBacon I'd like to avoid translating the simile as easily as a fish swims through water into any kind of rules text. I don't want to give the impression that, for instance, burrowing movement requires making Swim skill checks. However, if you want to write an answer that takes such a stance, that's cool. \$\endgroup\$ Commented Feb 17, 2020 at 22:53
  • \$\begingroup\$ @RevenantBacon As to the impact of earth glide and freedom of movement combined, you'll note that the answer leaves it in the hands of the GM; that's because whatever effect a freedom of movement effect actually has in a campaign is largely up to the GM dependent anyway and doubly so here (where, I agree, it typically should have no effect if the dude can already earth glide). \$\endgroup\$ Commented Feb 17, 2020 at 23:00

My first answer would be:

Try looking at the Paizo forum discussions about Earth Glide and see what you find. There are discussions about worked stone, carried objects, vision, and lots more.

Chances are, you're not going to find any hard rules on this issue. There's also a good chance that other sources can be found to contradict what you do find. Certain aspects of Pathfinder are intentionally left vague for the benefit of the DM. Others — this likely being one — are left blank simply as an oversight, because it's not likely that it will become an issue. Even if it does, though, it can simply be something that the DM makes a rule for. As rigid as some people think that the rules in Pathfinder are, it's the nature of any open-ended system to have situations the original creators didn't think about making rules for, and Pathfinder is no exception.

For this particular instance, my advice would be to use the rules for swimming as a base. Obviously there's not going to be a current, or anything like that, but it's just the ground work. Burrow speed would replace swim speed, and climb or another strength-based skill would replace the swim skill, if not a new skill entirely.

There will be questions you won't get answers to — not concrete ones, anyway — and my suggestion would be to just do whatever you think works best. Generally, I go with the rule of thumb that balance comes first, and fun comes second. Breaking the game will only lead to someone getting upset, but making a mechanic useless will lead to players regretting the decision to use it.

And remember, nothing is set in stone. *rimshot* But seriously, you can keep changing the ruling until it works for your group. There's no need to toss it out just because it didn't work the first time.
