Heiwa no Yubiwa [Ring of Peace]

Ishiyama Mukatsu (with his katana) can draw a symbol of peace around his allies, granting them the benefit of a short rest within 1 minute. This can only be used once a day.
Only the Samurai of Wa know how to manifest this aura of harmony...

* Inspiration from an ability used by Kana Soyokaze uses in
the Curse of Strahdanya: Legends of Avantris campaign
