Best weapons to take down Liches in shortest time

[PossessingSpirit09]

I'm really really just want my lich dead because him interrupting me while I play as well as the pressure of him always stealing me stuff is annoying.

I've been using a crit fulmin and tombfinger, and while I've been killing him quite quick, I'm pretty sure they're other weapons that do a better job.

P.S: Concerning the murmur parazon mods, yellow = correct. But what does crossed out mean? completely wrong? wrong order? I have 2 yellow, but the last I can't seem to get right, and I really don't want to have to die die die to get the combination right.

I found Vectis Prime to be pretty good for killing mine.
Using Octavia's mallet to distract the kuva lich makes it even easier to get headshots.

Crossed out parazon mods mean that parazon mod doesn't go in that specific position in your parazon's requiem mod slots to kill the kuva lich.

The stolen stuff isn't gone; it's just delayed until you finish him. It's still yours. Don't worry too much about it.

Check your lich's elemental resistances and weaknesses and mod your weapons accordingly if you want to kill it quickly. Beyond that, the weapons that do damage to it are the same weapons that do damage to anything else.

As for the mods, a successful lich kill sees you using three finishers on it, each after depleting a third of its health bar, and each one checks one mod at a time, from left to right. If a mod is marked as wrong, it might be elsewhere in the combination or it might not be there at all.

Since you've already guessed two mods right, it'll take at most six tries by trial and error to get the third one, assuming you don't repeat your guesses. The lich status menu lists all the mod combinations you've tried on it and their results. If you take out enough thralls, though, you won't have to guess, because they'll tell you the mods. They won't tell you the order, but with two right guesses, you already know the order.

In short, just keep running lich missions, killing thralls in the hope that it'll reveal the third mod, and try all the possible third mods that you haven't tried, keeping your first and second constant because they've been proven correct.
