1. S rank and below.
2. Well...from the wording of the technique, it says seals the technique. It doesn't mention size nor span of the jutsu so I'm assuming that it'll be sealed, even though Logic would imply that it wouldn't be able to.
Okay, so these two we just learn cover the basics of fuuinjutsu: sealing and unsealing things. From there, we move on to the specific forms of sealing.
( Fūin Fuda ) – Sealing Tag
Rank: B
Type: Supplementary
Range: Short-Mid
Chakra cost: 20
Damage points: N/A
Description: Once one of these tags is placed on an object, either by hand or by being attached to a kunai and thrown, a substantial seal slowly forms over the target. This prevents the target from moving or being summoned.
Note: The seal takes a while to form, so any opponent can rip it off negating its effects entirely, if he does so within five seconds.
Note: This technique only works against summons, or bodies resurrected via Edo Tensei.
Pretty straight forward, you place a tag on an item, either you hand or a projectile, and hit the target with it. Takes some time form as you can see. It's the jutsu used to seal edos in the manga and anime.
