Shaman Stone

Description
Said to contain the knowledge of past generations of shaman.

Increases the power of spells, dealing more damage to foes.

How to Acquire
Bought from Salubra in the Forgotten Crossroads for 220.

Usefulness
This Charm is estimated to double the damage of spells. Its usefulness, however, is somewhat debatable since in most battles, melee combat will be the primary source of damage and SOUL is best saved for healing.

Charm Interactions
Since using this charm is for spell-casting-focused builds, it can be useful in combination with Joni's Blessing in battles where healing is difficult or impossible.

It also works well with Spell Twister, which reduces the amount of SOUL necessary to cast spells, and any SOUL generation charm like Soul Catcher, Soul Eater, or Grubsong.
