The idea is to allow slaves to be summoned on your location, a bit like how the Transwarp system works. I suggest a item that can be gotten similar like the Transwarp items but for slaves only. This will resolves slaves that wonder off into space.

I can see how this can be broken so add some limitations like a aura of non firing for 10 seconds or something (at the developers discussion).

Summon slave transwarp: Sets your shields to 25% and your slaves shields to 10%.


Done!

How about both shields to 25% and a -resist effect? That way you can only transwarp them into safe areas
