This was a Live Games prize, I don't think it dropped from fishing/games/digging.
a sand-dusted paper
Invoking this sand-dusted paper will grant you permanent access to a special method of preparing your spells. It will provide the following phrase:
First Person: Amid a series of arcane gestures, your eyes burn briefly, and the sound of surf crashing into shores reaches your ears as you prepare the [Spell Name] spell... Third Person: Amid a series of arcane gestures, Roblar's eyes flash from bluish grey to bright indigo, and the sound of surf crashing into shores reaches your ears... Hidden or Invisible: You hear someone preparing a spell nearby as a cloud of silvery mist appears and wends its way upward in a spiral.
Abit more unique than some of the others found 696,969 times and could even work for Charl worshipers (outside the indigo) instead of just that evil eel lord Ghezresh..
