Summoning: Rising Minefield

First, the user bites into their thumb into it bleeds and writes the kanji for "mine" on the base of a summoning scroll. Then, after weaving the needed hand signals, the user unravels the long scroll which usually spans a distance of about fifty feet. Almost immediately after, a large multitude of mines similar to nautical mines used by ships to sinksubmarines are released from the scroll and fall onto the battlefield. One mine alone can blow a human body to pieces and create a well-sized crater, and when twenty or more gathered, a massive explosion follows that can erase the surrounding landscape of nearly everything. The mines are triggered by a hand seal, vibrations, and harsh impact. Depending on the situation, the user can have their opponents driven to the waiting mines by deception or force. If the need for use is dire, the can use a signal hand seal to detonate the mines at ready, best used when they are shot from the scroll and into the air. The mines also have kunai fixed upon them, so the knives are shot into multiple directions when the mine is detonated. This is useful when the inital explosion is survived or evaded, for the kunai are hard to dodge and are fired all at once.
