Ahh.. Jugo of the Scales, this is going to be quite a pleasant day.
Blizzard wields his newly mastered chakra of Ice, but this ice was not ordinary.. It was enveloped in the darkest power much stronger than anything ordinary. It started to snow in the battlefield, Right after making the black snow appear Blizzard channels his Earth chakra protruding a pillar from behind you which too gets covered with blackness.
[Hyouton: Kuroi Yuki] Ice Release: Black Snow Technique
Type: Attack/Supplementary/Defense
Rank: B
Range: All
Chakra: 25 (+15 per turn)
Damage: +10 to all jutsu made from Black Snow
Description: This technique is formed as a result of the user having used Ice Release: Glazed Black Ice Intrusion followed by Ice Release: Ice Technique(making it snow). As Glazed Black Ice Intrusion is a technique requires no handseal and that triggers itself upon sensing Ice or Earth Chakra of the user and manipulating it, Glazed Black Ice Intrusion can only be sensed by Doujutsu users and is triggered with the usage of an Ice or Earth technique, then followed up by Ice Release: Ice Technique that also requires no handseals, makes a very thicker than normal black snow fall across the entire terrain. The snow maintains the properties of Glazed Black Ice Intrusion, allowing all ice techniques made from the black snow have the extra resistance to lightning (takes a lightning jutsu of the same rank to cancel out any jutsu made from black snow) and a +10 damage to all black ice jutsu as a result, losing some of its damage from the former technique. In two turns, the ground will be completely covered in snow up to the ankles. . The user is capable of using the Black Snow to recreate/duplicate any Ice Release techniques that do no originate from inside the body of the user, by manipulating their chakra that is already inside of the Black Snow.
Note:

The user, can use this jutsu in place of creating Glazed Black Ice Intrusion and Ice Technique(to make it snow).

Other precipitation techniques (rain, snow etc) cannot be used at the same time as or used to cancel out Black Snow unless it is of a higher Rank.

Only the user of this technique can create other jutsu out of the Black Snow.

Another Ice user can post Glazed Black Ice Intrusion to use techniques from the Black Snow.
