Just had an idea for killing Undine, combining the Protonic Aresonal with the Biomolecular Torpedo.
Think on it, with the Set bonuses, the Biomolecular torpedo would have 22.9% damage boost + 20% damage boost vs. Undine for a total of 42.9 more damage vs. Undine, 20% accuracy, 15.5 crit chance (20% with pattern alpha), 10% extra crit severity, brutal damage.
The Dyson Set should also work well against Undine, 10% all energy damage resistance, and 20% antiproton restance.
Assuming we ever get Undine-heavy STFs this would certainly be interesting.
And I hope the Biomolecular torps will be available to everyone too.
Maybe a beefed up version will end up as one of the set rewards.
But the name is a pain and the shortened version, PABUK, sounds like a leprechaun.
I think that needs a bit of PR work.
