Sand Painting

These clear glass bottles of varying shapes contain layers of colored sand that form patterns when poured onto the ground or on a floor. A DC 15 Craft (painting) or Craft (sculpture) check is required to produce the effect successfully. Pouring the sand provokes attacks of opportunity. If the sand is disturbed while being poured, the effect is spoiled and that bottle is wasted. Once a sand painting has been poured from its bottle, it cannot be used again.

• Mandala of Peace: This conical bottle contains swirling, rainbow-colored sand. As a full-round action, the user can pour the sand into an ornate circular pattern with a 10-foot radius, producing a lesser globe of invulnerability and an area of silence within that area. The lesser globe of invulnerability lasts for 12 rounds, and the silence lasts for 12 minutes.

• Travelers' Oasis: This spherical bottle is filled with a layer of green sand on top of a layer of blue sand.

The oasis persists for 24 hours and supplies enough food and water for up to thirty-six Medium creatures or twelve Large creatures.
