I must disagree with the idea he needs a massive AP advantage to dismember his opponents in one shot. The minimum for one shot qualification is a 8X AP advantage, right? Bradley, Ling, and Lan Fan could handily dismember the homunculi they fought all the while not having a large AP advantage on their respective profiles.
Weapons like the plasma cutter, ripper, and line gun are effectively giant blades that could cut just as well as their swords. Even if we say he needs multiple shots to dismember Envy, that's nothing new to him. Plus he can still use his flamethrowers and explosives. And we see that even an injury can slow a Homunculus down or stun him. Hawkeye was able to suppress both Lust and Envy with gunfire. I don't think we've seen a Homunculus ignore attacks. The two exceptions being Bradley and Sloth with the latter being because the attacks kept bouncing off him.
Even Gluttony. When he attacks Hawkeye he waits for her to run out of bullets before he tries to eat. And when Fury shows up their gunfire causes him to start stumbling backwards.
In just about every instance bullets kept the homunculus in place until the ammo ran dry.
I see remake stasis isn't up there. Shame since you can get an upgrade that causes flesh to melt right off of bone.
Most of the weapons and crafting parts in his arsenal would be extremely effective here. This isn't a matter of some of the weapons are good against Envy. Most of them are good against Envy. But let's say that the weapons with small areas of effect cannot dismember Envy.
I'm gonna be using DS3 terms since you can remake just about all the guns in DS3. That does away with the military engine and telemetry spike primary fire.
That leaves the rest. Acid, stasis, and electricity will do a great job Many of the plasma core produces either does line damage or explosions. Tesla core either does line damage or electrocutes and since Envy is mostly human in composition eletrocution will still work. Survey charge are explosives and the homunculi have a history of getting destroyed by explosions. Rip core is effectively gives you a very long scifi sword. And we've seen that Homunculi don't like swords either. And the telemtry spikes have explosive and electruction seocndary fires so those will also be good as long as he makes use of secondary fire.
That only one that probably wouln't work is the force gun whic comes from the plasma core. It's a low damage high knockback but Envy should have high enough strenght to resist.
Yeah, if you slapped a weapon together by randomly picking out DS3 weapon parts chances are you'll land on something effective against Envy.
This gets even worse if we do away with DS3 weapons and focus on DS 1&2 since most of the weapons don't use the military engine or telemetry spikes. They use the plasma core, tesla core, or the survey charges. They use thigns that either cut in a line or explode.
It should also be noted the regeneration also has flaws to it.
The more grievous the wound the longer it takes to regen. Ling used this by detonating Gluttony then using the regen time to tie him up.
Also there's Bradley vs Greed. We see that you can overtax the regeneration. Later on in the fight Greed was struggling to stand from wounds that he was walking off just moments ago.
I'd also like to point out stasis has an AOE effect. So he doesn't need to hit Envy himself, he could jsut hit the ground Envy is close to.
Also, while this doesn't accurately reveal how much ammo it'll take to kill Envy, it's a reference.
If I recall, Bradley said he killed Greed fifteen times. Greed didn't die but he was beginning to show fatigue. Also he said kill. I'm guessing haphazard slices and dismemberments didn't count.
Ling and Lan Fan landed around 20 hits to Gluttony on screen. This includes dismemberment, decapitation, disembowlment, and just normal kicks and punches. While he didn't die, Pride admitted it wouldn't be long before he did.
Mustang bombed Lust 8 times in the final encounter before she died, 9 if you count when he was with Havok.
During their final encounter Mustang bombed Envy 21 times before he got turned into a worm. This is just the final encounter so we don't know how many times he got bombed both during the initial and during the chase in the halls. I also did not count the times Hawkeye shot him.
I counted 23 hits on Sloth. I included the ones that bounced off of him, the times he ran head first into the walls, and when Armstrong and Izumi's husband double teamed him I counted it as 2 hits.
