If you have points in Flow Capacitors and Partical Generators, and you're a Tactical Captain, it can do a pretty good amount of damage.

Although the drain doesn't seem to work properly, the radiation damage, when fired upon by energy weapons, does about 1k damage without buffs.

I use it with tyken's rift or power siphon combined with plasmonic leech, and npcs do shut down for a second or two. I'm fully skilled in flow capacitors, plus a few consoles and have 6 in particle generator.
I think by itself it won't do much. I use more as a support tool.

Have you tried it on it's own? From earlier in this thread, it sounded like Tyken's Rift was working. But two Aceton Assimilators will not drain a PVE ship.

Seems odd.

On their own two assimilators don't do much.
I just did a quick test in chos nebula against a galor on elite setting.
According to the powers bar they drain 29 energy each, do 49 radiation damage every second and 984 radiation damage when hit with energy damage.
Against the galor they did 5 damage per second when shielded and 42-50 damage when unshielded.
The galor did slow down quite a bit, actually enough that the two assimilators took down the facing shield, although that happened when the galor used fire at will.
Do enemies in pve have resistances?

Nothing I've ever hit with 2 Aceton Assimilators (both players and NPCs) has ever slowed down.

Also, if the power drain was working, it shouldn't drain their shields, just reduce their resistance. It's more likely that the radiation damage was weakening the shields.

Maybe it has to do with flow capacitor skill. In total, between consoles, skill and deflector, I have 227 points in flow capacitors.

-29 per second is so much that it should disable a pve ship in max 3 seconds.
If it was a static -29 to all power systems (like power siphon), 2 assimilators would be enough to do the same (or at least if ships have more than 50 power to all subsystems, which I doubt, they should move really slow as you can see when you drop a weak rank 1 tyken's rift).

I am pretty sure the drain doesn't work.
But like the 3p ground honor guard bonus, devs will never fix it for the 16% ppl who play KDF.

Maybe instead of -29/second, it's a flat -29?
Like leech is, up to -18, but not -18 per second if you know what I mean.

Either way a dev needs to confirm it's working one way or another.

Like I said, if it was a flat -29 then 2 assimilators should be enough to disable a pve ship (or at least slow him significantly).

It says in the description per second.
