magic ink

Exploration Stage: Antique Store
From: Alford Stone
Description: My protective tattoo spell has weakened and I'm worried. What if a witch tries to put a curse on me? I need to redraw the symbols. I need special charcoal to make the magic ink, used in the ritual. Will you help me find it?
Completed: You've taken a bowlful of charcoal from the druidic monk's eucalyptus wand! It is said that this tree has absorbed centuries of knowledge accumulated by the wizards of the forest. This charcoal can make a wonderful magic ink, so the sign you draw with it must have magical powers.
