Tamori has +3C while attaching Spells.
After you announce an action on one of Tamori's Spells, if bowing him is one of its costs: Give him +3C until it ends, and you will not ignore or substitute that cost.
"I have often been amazed by the skills of the Dragon shugenja, but Tamori has always surprised me with his skill, talent and strength." - Isawa Uona
