Istant Defeat Immunity

By defeating them through damage. Are you talking about the Rey boss battle with Ben on the team?

Hi crzydroid, than you for your answer.

No, I mean the Galactic Conquest in Normal mode.

At the end of the second sector, all enemies have a buff called "Istant Defeat Immunity" and I can't whin a battle anymore. There must be a way to win that I don't know :(

Please post a screenshot 

When you say you can't win a battle, do you mean that the enemies won't die? Say, they're stuck in the red at 1HP? Perhaps?

Hi Outrun Whistle

Yeah, you're right!

I didn't know how to explain (sorry but I'm Italian and my english is not good) but this just what happens.

All enemies go down to 1hp and don't die. Do you know how can I defeat them ?

Remove the training droids data disk.

….and read the description so you understand why you are having trouble defeating them 

Unequip the F-34T datadisk. You get a pass for English being a second language, but its purpose is to intentionally make the enemy unkillable (except through instakills) to make debuff farming for certain feats easier. However, many here don’t read the description and just equip it, then complain that they can’t win.

Tell me if there’s anything I’ve said you don’t get. Let me know if this helps!

Ok, I'm an idiot :(

Just removed the F-34T data disk, as you all suggested and.....Yes! I can kill everyone.

Thank you very much for your help, all of you. 

Next time I'll read the descriptions carefully :)

Understand that most of the data disks are better the higher their rarity, but that most of the Purple/Pink(?) disks are special & do different things, and that there's no lower rarity to it. Just because it's a higher tier doesn't mean that it's better by default. 

Google Translate:

Tieni presente che, per la maggior parte dei dischi dati, la qualità aumenta all'aumentare della rarità; tuttavia, la maggior parte dei dischi Viola/Rosa (?) è speciale, svolge funzioni diverse e non possiede varianti di rarità inferiore. Il fatto che un disco appartenga a un livello superiore non implica necessariamente che sia migliore per definizione.
