Cursed Seal of Mountains

The Cursed Seal of Mountains is the most powerful cursed seal amongst the seals used by the Takai Sect. Originally prohibited from use, the sect branded it onto Sōdai Shūshi-Bashira in hopes of securing his loyalty to them permanently. The opposite happened and with the cursed seal Sōdai destroyed the sect.

When used the seal turns its user's skin dark like other cursed seals and creates bone-like protrusions over the body. In the case of Sōdai it generated large cannon-like protrusions on his back that were capable of being used with his Lava Release.
