Healing Plaster

You purify some dirt or mud into a pliable,
claylike plaster that can aid in clotting and
healing. This restorative substance can be
used in lieu of healer's tools for Medicine
checks to Administer First Aid or Treat
Wounds. If the plaster isn't used within the
spell's duration, or if you Cast the Spell
again before using the plaster, it reverts to
being normal non-magical earth.
