Well, tbh, how you described your move I am not quiet certain it would actually work. Although snakes indeed have enhanced senses, sensing through that heavy of a mist would be a hard task. If mist was well modicum in amount, alright snake should be capable of sensing through it however in the case where it is heavy that shouldn't be possible. Anyhow, let's get going. Performing few seals, chopping a small portion of skin on her finger and slaming her hands onto the groud whilst releasing chakra Akasha would make a sealing formula appear with the smoke to follow it. As the smoke vacates, a huge snake appears. Manda! Try and tell me something about this summoning.
(Kuchiyose no Jutsu: Manda) - Summoning Technique: Manda
Rank: Forbidden Rank
Type: Offensive/Defensive
Range: Short
Chakra cost: 50
Damage points: N/A (-10 to user upon summoning)
Description:
Manda is a gigantic, 100 meter long snake who serves as the "leader" of all snakes. Fierce and aggressive, Manda is a shrewd warrior. To summon Manda, the user takes a big gamble, as he can easily turn on its summoner if he so deems it. Not only that, but the sacrifice and the amount of chakra needed damages the user, making summoning Manda a forbidden act. Manda has some unique abilities. Extremely fast and strong, his tail acts as a sharp mace that he can fling at the enemies with ease, speed and tremendous power (capable of overcoming even A-Rank defenses). Manda is also capable of using his chakra for 2 unique techniques: he can borrow underground (even if its affected by up to A-Rank techniques), tunneling through the earth at enormous speed or shed his skin, using a sort of substitution technique, where he trades places with his shed skin. While underground, Manda can sense the vibrations through the earth and pinpoint the location of his enemy. While completely immune to techniques A-Rank and below, Manda can take one S-Rank attack and survive by shedding his skins afterwards, although this can only be done once.
Note: requires snake contract
Note: can only be summoned once
