(Doton: Iwayado Kuzushi) - Earth Style: Rock Lodging Destruction
Rank: B
Type: Offense
Range: Short/Long
Chakra Cost: 20
Damage Points: 40
Description: The user performs the required hand seals Tiger → Rat → Snake and they then causes a cave-in by destroying the equilibrium that holds the cave together. Just removing a single vital stone throws off the balance of the cave, making it unexpectedly fragile and causing a domino effect that destroys the entire cave. The shinobi from Iwagakure use this technique in their pride tactic, luring several enemies into a cave to kill them all at once
Dislodge a few stones, and cause a cave in aiming to crush your opponent. This one can be useful, but there are rarely fights that make their way into caves, so it's also highly situational.
(Doton/Katon: Yōdo Ranfunka no Jutsu) - Earth/Fire Release: Molten Earth Wild Eruption Technique
Rank: B
Type: Offensive
Range: Short - Mid
Chakra cost: 20
Damage points: 40
Description: The user will stomp the ground to lift of chunks of rock which he will then send at the opponent. Then, by using a fire style technique, he will cause them to ignite into burning rock chunks which explode on contact with the enemy
Make a few chunks of earth rise and fly toward your opponent, then use your fire chakra to ignite the chuncks, making them each a contact explosive. Pretty straight forward, so I'm not going to add much, except just a elemental advantage/disadvantage reminder. Earth is strong to water, while fire is weak to it. Because this technique is listed as both, you have to consider the elemental implications here, which would be that it would be neutral to water techniques. So basically you lose your elemental advantage.
