This is the Hunters Thorn keyblade. It specializes in healing and wind magic (although it's mostly used for healing because he isn't great at blocking hits).

The formchange is a Scythe called Nature's Thorns, which when hitting the ground, causes healing green hexagons to show up. When an ally steps on said hexagons, they will be healed instantly and the spot goes away. But if an enemy steps on them, they will be hit with a gust of air. The finisher is a powerful healing spell with bursts of wind surrounding Skeith.
It has the lead bracer ability.
Its shotlock has the thorns on the blade extending outwards and hitting enemies surrounding Skeith.
