Sage Art: Yasaka Magatama

While Jukan is in Sage Mode, he molds chakra in his abdomen except the chakra gathers in between his hands akin to the way holds a Rasengan with two hands. When completed, the conglomeration of chakra-turned-fire forms into a tomoe shape. Jukan could then throw the completed jewel which would explode and engulf a 20-foot diameter circle. The explosion is in the fashion of a cone with the top portions slightly curved inwards.

Drawbacks
One big drawback is that Jukan needs at least ten seconds to prepare the technique. In that ten seconds, he could be easily struck down.
