Sparks chain mechanics

So my concern is the interaction of a chaining spark with the projectile rearm time and the anti-shotgun timer. Following scenario:

Spark projectile A hits mob 1 and chains to mob 2. Mob 2 was previously hit by Spark projectile B, so mob 2 will be hit by projectile 1 before its rearm time (1000 ms) and the anti-shotgun timer (350 ms) is completed. What will happen?

I would guess it will just go through.


And what happens if only one timer is not completed. So if projectile A chains to mob 2 and

1) The anti-shotgun timer is not completed

2) The rearm timer is not completed

What happens in those 2 cases.
