(Ninjutsu: Kemuritadai no Jutsu) - Ninja Arts: Heavy Smoke Technique
Type: Supplementary
Rank: B
Range: N/A
Chakra: 20
Damage: N/A (+10 to Smoke Ninjutsu)
Description: When preparing a Smoke technique, the user makes two extra handseals and adjusts the ratio of particulate matter within their initial technique. The increased particulate matter causes the smoke to become much thicker and heavier, giving it a darker gray tone. And due to the increased weight, the user's smoke hits with more force than is typical. In addition, this process will negate Smoke's standard weaknesses to both Water and Wind.
Note: Only useable by bios that've learned Smoke Ninjutsu.
Note: Only useable four times per battle.

Now in this technique, you will make two extra hand seals with a Smoke technique. This causes the smoke to become thicker and gray in color. It also becomes heavier, and due to this, the smoke causes more damaged and negates the weakness to Water and Wind. Only usable like 4 times.
