Morlock Creeper how to use Sneak Attack Swarm ability at range?

[Shadolrdsfallen]

With Morlocks in general they have the Swarm ability to gain Sneak Attack when in the same space.
Creepers have +4d6 Sneak Attack, and use Blowguns.

If 2 Creepers are in the same space they get the Swarm Sneak Attack, but how is this played out during ranged combat?

Do they have to be within 30 feet of the Target?

Do they get to use the Sneak Attack Damage on all attacks when they Swarm?

Does the Target of the Blowgun attack have to also have some other opponent that is already Flanking them, or does the Swarm ability of the Creepers take effect without anyone else flanking the opponent?

How have others dealt with the Creepers during combat?

Thanks!

The swarm ability literally means they are considered flanking when in the same space as another allied creature with the swarm ability. Typically, unless you have an ability that allows you to threaten with a ranged attack (like snap shot, which must be within 5', or with Improved snap shot within 10'), swarm would not give you the ability to sneak attack with a ranged weapon.

But, if they did have improved snap shot, then they absolutely would get the sneak attack within 10' when swarming kicks in. And the sneak attack would apply for every single attack that complies with the swarming, flanking and threatening rules. This is not an instance like hiding or invisibility where only the first attack would be a sneak attack.

Also flagged this as being in the wrong forum, as this is a rules question, and not so much an AP question.
