I believe if you attack with another jutsu it stops Infinate Embraces. Though if you manage to have another entity try and hit the barrier yeah you'll just break it :/ kinda wank. Best try and manifest something inside it with your wind release ;D
Well according to sasori two seals that are linked to each other ain't Fuuinjutsu so good luck with customs like that
Very useful Seal coming up;
( Fūin Fuda ) – Sealing Tag
Rank: B-Rank
Type: Supplementary
Range: Short
Chakra cost: 20
Damage points: N/A
Description: A basic sealing technique where the user places one or more tags either directly on a target or on a technique which is restraining it. As its placed, a sealing formula spreads around the technique or the target, sealing it. This technique has been seen used with Sand ninjutsu, Earth, Water, Wood, Cloth Ninjutsu, etc but basically any technique in which you can apply the tags can be used. In the case of expert ninjas, the tags might even be incorporated into the restraining technique, with no need to actually manually place the tag or tags. Additionally, less experienced ninjas can find that throwing one or more kunais with the sealing tags attached at the technique which will trigger the same effect when the kunais stick on the technique. This prevents the target from moving, molding chakra or even being summoned.
Note: The seal takes a while to form, so most opponents can either counter the restraining technique (thus preventing the sealing formula of taking effect) or rip off the tags from themselves negating its effects entirely. If the target, however, fails to counter the restraining technique or is counter to it fails or if he doesn't remove the tags in his next move, then the seal will fully be placed and the target unable to release himself.
Note: This technique is specially designed to be used on summons and Edo Tensei Summons but will work on any opponent except Jinchurikiis.
( Chakra Haisui Fūin no Jutsu ) – Chakra Suppression Seal Technique
Rank: B-Rank

Damage points: N/A
Description: The user places this seal on the forehead of a Jinchuuriki influenced by the powers of a Bijuu, to forcibly cause the Bijuu's powers to recede. The Jinchuuriki becomes exhausted after this happens.
Note: This can only restrict Jinchuuriki in their Incomplete form, not when they completely transform into the Bijuu.
( Han'you Fūin ) - Generic Sealing Technique

When needed, the owner will activate the seals releasing their item or weapon of choice. Scrolls can also be used as ammunition for other weapons. The items themselves are unaffected by time. This Technique allows the user to seal any weapons they wish being their own or opponents.
