As of now, the Withered Symbiont has a chance to fall down the hole in the Command Block fight. When the storm is defeated, said Symbiont wanders the wasteland left behind by the storm. Once it attacks again, it uses command block related attacks like pulling and summoning arrows. This makes no sense from a continuity prospective, since it has nowhere to derive said powers from. Therefore, any naturally spawned Symbionts should not be able to use those attacks in general besides their melee and possibly their slam. For simplicity sake and for gameplay reasons, they should outright shut down. Artificial Symbiotes should be unaffected by this to make creative mode chaos not ruined when entities need to be killed.

An easy way to implement this is to add a Boolean tag [NaturallySpawned] and set it to true if spawned by the Wither Storm or the Command Block. If a command block dies (excluding the playing dead decoy one) then it should activate the inactive state protocol, shutting down all Symbiotes summoned by the storm.

this is an good idea

I love this idea

very good idea

adding to this, symbionts always jump up when being hit, if the player want's to kill the remaining symbionts, maybe something could be done so they don't just jump far into the air and smash down, like they normally do. idk just a thought

One problem I have is that it might load too many chunks perhaps this could be fixed by having the symbionts health slowly deplete as the power of the command block book starts to fade and they have no way to replenish it with the wither storm gone perhaps death from the absence of the wither storm will not have the death animation and just hunch over as they turn to smoke they could drop a normal book to show that it was once a command block book but ran out of power they could also lose some attacks and have a fainter purple glow as their power depletes.
