Meld into stone enables the character to meld the character's body and possessions into a single block of stone. The stone must be large enough to accommodate the character's body in all three dimensions. When the casting is complete, the character and not more than 100 pounds of nonliving gear merge with the stone. If either condition is violated, the spell fails and is wasted.

While in the stone, the character remains in contact, however tenuous, with the face of the stone through which the character melded. The character remains aware of the passage of time and can cast spells on him or herself while hiding in the stone. Nothing that goes on outside the stone can be seen, but the character can still hear what happens around the character. Minor physical damage to the stone does not harm the character, but its partial destruction to the extent that the character no longer fits within it expels the character and deals the character 5d6 points of damage. The stone’s complete destruction expels the character and slays the character instantly unless the character succeeds at a Fortitude save (DC 18).

At any time before the duration expires, the character can step out of the stone through the surface that the character entered. If the spell’s duration runs out or the effect is dispelled before the character voluntarily exits the stone, the character is violently expelled and takes 5d6 points of damage.

The following spells harm the character if cast upon the stone that the character is occupying: Stone to flesh expels the character and deals the character 5d6 points of damage. Stone shape deals the character 3d6 points of damage but does not expel the character. Transmute rock to mud expels the character and then slays the character instantly unless the character succeed at a Fortitude save (DC 18), in which case the character is merely expelled. Finally, passwall expels the character without damage.
