For which, the running out of ammo or dying in Nightfall? If the latter that is really good to know for when I start running them.He is correct, but it's not a full refill, just a partial...like 30% to full capacity I think.
The "run out of ammo" thing is a red herring though. Running out of ammo means you've been pelting a boss with your primary weapon instead of shooting rockets at it which is what the extra ammo allows you to do.
Okay... um. *shrug* Being able to do it without using them doesn't mean it's not a good idea. You can cut down on your boss kill times significantly using these.In the nightfall you won't receive heavy ammo when being revived, only primary. But I always just use that to kill the smaller adds (acolyte, thrall, etc) and then pick up heavy ammo from them. I've never once used Ammo synthesis in the 2 times I've gone through Nightfall.
