I heard you can spawn bloatflies using the glands they drop and a syringer.


My question is, do they spawn just firing syringer or do you need to hit a target for a chance for them to spawn?


If you can just spawn by fire it is my intention to make an arena in where new settlers who wosh to stay in my settlement must fight waves of these beasts unarmed. Survivor gets a place within sanctuary hills, with their own house.

I'm also curious about this, also your arena idea is very creative!

Thank you

According to http://fallout.wikia.com/wiki/Syringer_ammo, it's a chance on death for the target to spawn a bloatfly.
