A rare item gained from an npc that when used will randomly choose an npc that has been alerted to the legion within the past 24 hours and give another one of them to fight.

i'll leave somebody else to think up a name for it

The Quantium Displacement Bomb.

Pulls a NPC alerted earlier from an alternate universe that won the battle againist your teammate.

What about a exetremely rare NPC that drops a power source unlike anything your scientist have ever seen.

It give your ship unlimited energy for one to two minutes ONLY fighting NPC and NPC bosses.

What do you guys and gals think?

Naah too much ...uncommon npc that awards 100 energy on kill.

if shield recharge and repair nano drone and tri ma.... wait that fills energy too..
just shield recharge and repair nano drone, anyway, if those cannot be used during the duration of this, then it's fine IMO. Because it will only allow you to dump until 2 bars of ur hull and 1 bar of shield are gone. So where it's possible that it's still a lot, it's still fairly limited
extremely rare justifies it I think.

wouldn't mind a few minutes of unlimited shield output...
(temporary invincibility to bases!!)

maybe 2 minutes of invincible shields, followed with shield burnout (0% shield and unable to use shield restorers) for 10 minutes

That would be a great one too for the bases. Excellent suggestion.
