Good work man.
There is one D-rank left, but I need to teach you a C-rank for you to use it.
With that, I would like you to use list some advantages and disadvantages with the performance of the techniques if you please.
(Doton: Moguragakure no Jutsu) – Earth Release: Hiding like a mole technique
Rank: C
Type: Supplementary
Range: Long
Chakra cost: 15
Damage points: N/A
Description: The user changes earth into fine sand by channeling chakra into it, allowing the user to dig through it like a mole. While underground one can sense what is happening on the surface and use the information to launch a surprise attack on the enemy. Once can also hide deep in the ground, escaping to a depth where the enemy cant reach. It also appears that after digging, the ground can be returned to its original state, leaving no trace of where the user entered the earth. While inside the earth, the user cannot make handseals and can only use Earth techniques below C-Rank. If he tries to do a higher ranked technique, he'll disrupt the Hiding like a mole technique and be left crushed.
Fairly simple technique and a good technique to escape techniques, use your doton chakra and channel it below you into the earth, doing that will change the earth into a fine sand, which allows you to slip into the earth. Only downside with this technique is you cannot use techniques that require hand seals, but you can use earth techniques that require no seals, and are C-rank and below.
You cannot use any other elements while underground. Otherwise the earth above you will collapse and kill you.
