Hence the name, the user uses the water vapor in the air to form compacted snowballs. They materialize right beside the user, hovering in mid-air. The level of compaction that the snowballs have can vary depending on the chakra usage of the user. When these snowballs are hurled, either manually or mentally, they can cause severe damage to anything that comes in its path. To humanoid targets, they can cause internal as well as external damage, and have the chance of killing their target. However, because their density can be changed, these snowballs can be also a form of entertainment, such as a one-sided snowball fight.
