Yep, you need to raise and point them away from your body, and keep them perfectly straight. And on that note, if anything manages to prevent you from keeping your arms positioned in this way, the technique will fail. And yes, both Judgement and Greater Dark Release would overcome C-Rank Earth and Water. B-Rank would neutralise both. Now, onto the S-Ranks. These are just superior versions of techniques you see in the previous ranks, so if you understand them, you should understand these too.
(Meiton: Kyūkyoku no Kyūketsukō) Dark Release: Ultimate Inhaling Maw
Type: Defensive
Rank: S-Rank
Range: Short
Chakra: 40
Damage: N/A
Description:
The user, when facing an attack, will clap his hands together and separate them right after. As he separates his hands, a small dark sphere will be between them. The user maintains his hands close to sustain the small sphere while it siphons any enemy technique or enemy chakra within range towards itself. The sphere is a "void" made by activating both absorbing markings in the users hand at the same time and opposing them to each other, which creates this effect. This technique is essentially a more advanced and powerful version of Dark Release: Inhaling Maw and enables the user to absorb higher ranked techniques. However, when used, the user needs to wait one turn to use Dark Release absorption related techniques.
This basically allows you to absorb whatever the normal Inhaling Maw and Netherworld Gates cannot. Visually speaking, performing this technique is very similar to how the Deva Path formed the sphere of gravity in his hands when using Chibaku Tensei. The sphere in this technique is simply a mass of Dark chakra connected to the user's palm seals.
(Meiton: Kyūkyoku no Jajjimento) - Dark Release: Ultimate Judgment
Type: Offensive
Rank: S-Rank
Range: Short-Long
Chakra: 40
Damage: 80
Description:
A stronger version of the Dark Release: Judgment technique, the user will convert the absorbed chakra from either two uses of Dark Release: Inhaling Maw or one use of Dark Release: Ultimate Inhaling Maw and then releases it into light blue flames, turning it back on their enemies with amplified strength to blow them away. To do this, the user releases chakra from the markings in both his hands.
Note: Must have absorbed enemy techniques before using.
A stronger version of Dark Release: Judgement. Take note of the requirements for performing this technique.
(Meiton: Chō Kasseiken) - Dark Release: Super Revival Fist
Rank: S
Type: Offensive
Range: Short
Chakra cost: 40
Damage points: 80
Description: This jutsu works in similar fashion to rasengan. By releasing and gathering dark chakra into one of the users hands, the user can create a dark orb with two dark rings around it (giving an atomic look). The user will then plow the orb into the opponent, resulting in the opponent being with tremendous bone shattering force.
Note: Must have absorbed enemy techniques before using
This technique, like Ultimate Inhaling Maw, is slightly different from its lower-ranked counterpart. The normal Revival Fist simply allows you to launch a shapeless, though visible, blast of energy at a target. This technique, as stated in its description, is similar in form and nature to the Rasengan. Think of it as, because the energy is more focused and stronger, it takes on a more defined, condensed form.
