Effect By stamping your foot on the ground and calling out to spirits of stone, you summon a stone wall. This is a wall of stone, except that the wall is tied to your own life force. When the stone wall is damaged, you are damaged instead. If you are reduced to 0 HP, the wall is destroyed. The effect is dismissed if you move more than 30 feet away from the stone wall or if you spend a single action with the concentrate trait.
Traits
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.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
