Arijigoku

[Hopalong]

I have a question about the jutsu below

Arijigoku (Inescapable Hell) (325)
Rank: D, C, B, A, S
Type: Supplementary / Doton Ninjutsu
Range: See special!
Handseals: Yes
Chakra: D - Low, C - Mid, B - High, A - High, S - High x2
Special: Creates a crater underneath a victim within the user's 'Doton Ryouuken' range which sucks them in deep underground. Distance at which they could be sucked in depends on the user's 'Doton Ryouuken' distance. Crater always will be slightly larger than the victim that's being absorbed.



D: Full post suction

C: 3/4 post suction

B: Half post suction

A: 1/4 post suction

S: Near-Instant!

Description: Doton • Arijigoku is a Ninjutsu utilizing the Earth Element. After forming the needed hand seals, the user will create a conical crater below their opponent that serves to suck in an opponent. If trapped, this twisting, sinking pit will pull the target below ground to imprison and suffocate them.
Domain: Doton. Doton Ryouuken of equal rank.

When you cast the jutsu, does the crater itself span the range of 'Doton Ryouuken' or the crater may be cast anywhere within the user's range?

Crater always will be slightly larger than the victim that's being absorbed.

It can be cast anywhere within the user's range.

Alright, extra question. If I use Iwa Bunshin:

Iwa Bunshin (Rock Clone Technique) (150)
Rank: C x3
Type: Supplementary / Doton Ninjutsu
Range: See special!
Handseals: Yes
Chakra: Mid
Special: Up to one clone can be made at a time, plus one more each time retrained. Being elementally based, this clone is capable of using any c-rank and lower Doton techniques the users knows. Can be relearned up to 4 times for a maximum of 5 clones created.
Description: Doton • Iwa Bunshin no Jutsu is a Ninjutsu that utilizes rock to create a Bunshin clone. Unlike a normal Bunshin, the Iwa Bunshin has the ability to interact more with the environment due to it having physical substance. This allows the clone to carry out limited attacks on its target, especially with its rocky earthen frame, adding power to its attacks.
Domain: Doton. Doton Ryouuken 'C'.

Obviously I'm limited to C rank jutsu. However, can I use jutsu I have ranked up to A, such as Arjigoku, but restraining it to C level power (i.e: 3/4 post suction)?

[Naitome]

If your C rank rock clone can use earth techniques you know up to C rank, then yes, it can use the C rank Arjigoku that you know.
