Stonewall

A creature with this trait is a member of the dwarf ancestry. Dwarves are stout folk who often live underground and typically have darkvision. An ability with this trait can be used or selected only by dwarves. An item with this trait is created and used by dwarves.

Effects with the earth trait either manipulate or conjure earth. Those that manipulate earth have no effect in an area without earth. Creatures with this trait consist primarily of earth or have a connection to magical earth.

These effects completely transform the target into a new form. A target can't be under the effect of more than one polymorph at a time. If it comes under the effect of another, the second effect attempts to counteract the first. If it succeeds, it takes effect, and if it fails, the spell has no effect on that target. Any Strikes granted by a polymorph effect are magical. Unless otherwise stated, polymorph spells don't allow the target to take on the appearance of a specific individual creature. If you take on a battle form with a polymorph spell, the special statistics can be adjusted only by circumstance bonuses, status bonuses, and penalties. Unless otherwise noted, the battle form prevents you from casting spells, speaking, and using most manipulate actions that require hands. (If there's doubt about whether you can use an action, the GM decides.) Your gear is absorbed into you; the constant abilities of your gear still function, but you can't activate any items. You lose your Speeds and gain those of the battle form. If a polymorph effect causes you to increase in size, you must have space to expand into or the effect is disrupted.
