The Sentinel

I feel like this ability has been done before but here‘s what I made. Hope this isn’t too overpowered.

Stand Name: The Sentinel

Localized Name: The Sentry

User: ???

Namesake: The Sentinel – song by Judas Priest

Stand Type: Close-Range, Artificial-Humanoid

Stand Stats:

Abilities: 

While The Sentinel is a Close-Range Stand, it possesses 10 razor-sharp throwing knives that can be thrown at enemies.

Each knife takes around 10 seconds to regenerate.

Synchronization

The Sentinel has the ability to sync two beings by slashing them with the same blade and mixing their blood. The targets must be within 10m of each other, as both people will be shackled at the neck and chained together with a 10m long chain. The user cannot sync themself with a target, both beings must be the same species, and the user can sync no more than two beings at a time.

By chaining two people together, any reaction, sensation, or damage experienced by one will also be experienced by the other. For example, if one person feels nauseous and vomits, so will the other. If one person becomes drunk, so will the other. If one person is stabbed in the heart and perishes, so will the other. However, this doesn’t apply to anything before the ability's activation. If a person had a cut before being synced, then the other person will not received said cut. 

The user takes advantage of this ability by connecting a strong or stronger opponent with a weak bystander. This forces the target to divert their attention towards protecting the person they’re tethered to. If the bystander is killed, then the target will be killed by the abilit.

The synchronization can be removed by defeating the user or by baiting The Sentinel to break the chain. Any attacks made on the chain by anyone else will be redirected to both victims.
