+punch through:
Pretty meh, one could use primed firestorm, +shred being decent/good on soma.
+damage:
While not worthless, +damage is pretty much irrelevant in the current meta. You have a free damage "mod" with the arcane slot, and the galvanized status mod.
+elec:
Good, +elem damage is good in the current meta. But it's not the right element. Cold/toxin would free a mod slot for viral, heat would be better than elec.
So overall, pretty meh (which means useless it practice, since someone will always want something at least good). You have maxed it, so it's worth the endo cost. Around 40p on PC.
So you want a weapon build? Max strength with the 1 augment, probably roar with helminth for the high proc damage on the 3. Get a high enough duration so that you don't need to spam your abilities too much.
On the weapons, go for viral heat. You will have the Holy Trinity of Elements, corrosive/viral/heat, plus toxin with a guarranted proc. With the new galvanised status mod, you can easily reach absurd amount of damage.
The usual use case of limbo is press 4 press 2 in missions/events where killing things doesn't matter (stuff like excavation/mobile defence).
You want high duration and usually low range, but high range can also be interresting with his 3 and 4 augments.
I don't own the Kuva Zarr, so I can't test what I say, but here's what I think.
You should farm the new galvanized mods, this will let you free at least one slot:
Replace Split Chamber with Galvanized Chamber, and you can safely remove Vigilante Armaments.
Then, you can probably use Galvanized Aptitude and remove both Serration and Heavy Caliber. The base status chance is high, and you can proc with the impact, the explosion, and the second explosions. You have base impact and blast damage, you should get enough different status effect to have enough bonus damage to safely replace these 2 damage mods.
This leaves you with 2 free slots: Hunter Munitions which should be here anyway, and either a Primed Bane Mod or Primed Firestorm. You can also keep Serration if Galvanized Aptitude is not enough, as I said I didn't test. You also have the new Arcane slot for +damage, so even if Galvanized Aptitude is not enough, Serration shouldn't be here in the perfect build, but I assume you don't own the arcanes yet.
In the end, replacing +elec with +cold or +toxin would free another slot and let you build both Firestorm and Bane, but it's not like you can't build your weapon with +elec.
On a side note, I am pretty sure you can chose which weapon and which element to keep separately now.
No vigilante mods? No kavat?
The meta is still slash procs.
Raw damage builds now have access to galvanised argon scope when slash builds don't, but the amount of weapons that can actually kill with headshot is pretty low, even when you build for it
So if your goal is the easy kills, you should stick with a random explosive crit weapon with hunter munition, bane mod and maybe viral, or use your melee.
On average you need 80 kills, that's 20 rotations without missing any node. But in the end, it's rng, you may need less, you may need more.
Oh, i'll look into it.
Edit: Indeed. Then, the viral build is not that bad (you still probably want that 60 60 though), and will actually be better the longer you shot (ie, the longer the enemies survive).
"the Hunter Munitions bleeds are dependent on damage"
That's where you're wrong. I suggest you take a look at the slash proc damage formula. Only the base damage and "moded base damage" count towards slach proc damage (ie, not mods with +ips or +elemental). And faction mods, and things like rhino's roar, which count 2 times, because why not.
Also, viral procs doesn't apply to the slash procs that where there before them, so even if you can reach max stacks with your build (it would require an average of 60 shots, but you can definitly get it with a single load now and then), the amount of shots that will really benefit from them won't be that great.
Try your build without your viral (with nothing to replace it), it won't be that weaker.
And if you still decide to go for viral, try with 1 or 2 60 60.
At least replace your 90 with a 60 60.
Your current viral chance (with the galvanised chamber fully stacked) is 14.26%, which means the first 6 bullets (on average) you shot at someone won't benefit from 2 mods of your build.
With a 60 60, you jump to 21.78% (and with 2 of them, 23.76%). Which is still garbage imo, but decent enough if you really are a viral fan.
My build isn't exactly up to date, you would replace point strike with critical delay, and vigilante is no longer relevant, so you can put whatever you want, probably vile acceleration.
You build hunter munition + primed bane mod right? Viral acceltra has a status chance a bit too low and doesn't work that well.
Acceltra is one of the best weapon in the game, and is definitly strong enough for steel path, especially with the new multishot mod.
If you don't have access to the good mods, use a buff frame like chroma or saryn, or use a melee weapon.
I am pretty sure this bug was fixed, maybe DE reintroduced it somehow?
As a "fix", you can play as the host. 90% of warframe bugs don't affect the host.
Each of these mods should have a page on this wiki, with all the information there is to provide about them.
You can get Umbra in the quest The Sacrifice.
Excalibur Prime was given to the players who supported the game in its early days, you can't have it now.
We are talking about melee weapons here, there is no reason to not go for both crit and status. Even a weapon with 10% in each stat would be enough to proc crit and status most of the time.
When a new prime is out, the set is usually worth a few hundred plats the first hours, and drops to around 100p just after that. Wait 1 or 2 weeks, and it should stabilize around 40p (PC prices).
Since it's a game where you can and often want to collect every items, new items won't change the price of old items. More precisely, the fact that an item is stronger than another won't affect prices, only rarity will (except for rivens obviously).
Since it has corpus origin, it would be a vandal or maybe prisma variant, not prime. But yeah we would probably get one (most items receive at least 1 variant), not soon though.
Warframe market is essentially the same as the ingame trade chat, except that instead of seeing offers for only 10 minutes or so, you can see all the current offers, and you can sort them by price. This means you can always buy something at the best price, as long long as you don't include scamming into the best price.
Indeed, since this app will show to everyone what is the current lowest selling price for any item at the current time, people can consider that price as the "real" price of an item at the current time. This mean it will be harder to scam people buy asking them to sell that item at a lower price, or to scam them by asking them to buy it at a higher price. Maybe this is a problem to you (and I don't mean that in a wrong way, scamming people is a legitimate thing to do in a free market), but other than that, I fail to see why someone would have any problem with this app.
What you are saying doesn't make any sense.
Someone who look at the WTB category would be looking for the highest prices, not the lowest. So your bunch of people posting fake trades would just be ignored.
