If you're looking for a very short summary, here it is:
This weapon is horrible.
If you want more, continue on.
I have a highly specialised set for C42, which is a Dragon Scale set with poison and fire low UVs. This grants me immunity to most statuses in the mission. It would be great if I can carry a sword that is maxed in terms of damage against Gremlins and Slimes. Damage trinket + gremlin H UV + perk will be adequate.
The overall damage of this weapon however is unsatisfying. Acheron is still far better even against slimes. To put this into context, a Combuster does more damage to wolvers when fire is accounted for than this weapon, which supposedly should be better.
It also staggers me that the Amputator require Zee Cores, all while having nothing to do with the sleep status at all. It doesn't even do sleep! I personally think all normal swords are underpowered. I don't mind to be honest, but adding a sleep status to the charge will be great.
Anyway, it looks kind of cool, so there's that.
"This weapon is horrible."
Or to be more specific, It does the same damage as cold iron vanquisher but it's a brandish.
"I personally think all normal swords are underpowered.
I recently came to the same conclusion after using this weapon, and calculated that a 14-16% damage increase would elevate 3 swing normal swords to brandish levels of alright against neutral targets. Ergo, I suggested a 15% normal damage buff to all normal weapons, such that all normal swords are in the ballpark of "useable".

I'd personally rather they did away with the whole normal but with damage to x balancing mechanic as well, and just give those weapons status effects with their damage vs x bonus as a free extra.
"Anyway, it looks kind of cool, so there's that."
Totally with you on that as well. It seriously looks ready to take a chunk out of 'em.
