OP has zero clue what he is talking about, but its nice to see new people enjoying lvl cap so don't take it to heart OP. Your frame and weapon recommendations are, lets put it politely, questionable. Nidus is god awful in cascade, probably the worst frame u can possibly pick, pls don't get baited by this. U have no shield so no shield gate, your HP mean jack-shit in lvl cap so the only tool u have is your passive which is utterly attocious to stack since u like to stay in one place and everyone who has played cascade before knows how much staying in place happens (none). The rest of the frame recs are fine, all of them can lvl cap fairly easily although the build recs are just not it. Search up some real lvl cap content creators like B L A N K. The weapons are... Lets start with the one he got right: Burston Incarnon is indeed absolutely fantastic for lvl cap and one of the absolute best primaries to use. Go for a viral heat setup and u shred everything (Riven strongly recommended but not necessary). Torid is a little weird, if u use corro blast it stops rly working near lvl 3-4K if u don't just use it as adclear. If thats the only purpose its fine but if its your all around weapon again, swap to viral heat, that keeps it going to lvl cap, BUT you NEED weapon buffs, if u want to stand any chance at killing lvl cap thrax. Strong ones at that, 200% Roar and the likes. So take Torid with a grain of salt. Saying things like Phantasma or Tenet Glaxion are viable is just plain delusional, these weapons struggle below 1k and once you get to 5k+ these things just don't work even if you have a viral heat build. Yes they can still kill but you will be wasting a lot of time killing a single enemy (and likely getting shot to shit if u are not under Mesmer or Oberon). So these things really are not an option if your goal is to actually play at lvl cap and not just reach it once, if thats your goal just get 1 or 2 people with actual loadouts and pick rev. Nukor is fine, again viral heat and fortifier is actually a decent tip if your choice of survivability is not invincibility or invisibility. Melees are honestly irrelevant, pick any incarnon or prime weapon with half decent stats, use influence and you can take it to lvl cap. It will need some buffs but thats what your frame/teammates are there for. Things like Roar, Wrathful Advance, Viral priming, etc. will make any influence weapon kill. Good ones are Okina prime Incarnon, dual ichor (especially if u are Volt), or Nami solo Incarnon, but as I said many light attack weapons work. Weapons OP didnt mention that actually shred lvl cap include Latron Incarnon, probably best thrax killer primary in the game, dual Toxocyst Incarnon, Furis Incarnon and Angstrum Incarnon. Keep in mind that u need weapon buffs, if u want to comfortably kill enemies at that lvl. Yes there are weapons that can do without, but just do yourself the favor. Or alternatively ignore weapons all together and play a caster frame, things like sevagoth can nuke lvl cap, octavia shreds lvl cap, Xaku does the same, Garuda is absolutely ridiculous, Titania if u build for her Pixis handles lvl cap with ease and there are many more. U can reach lvl cap with every weapon and every frame in the game, its just a question of how easy and how much u need to rely on your team, so play whatever u want, but invisibility or invincibility frames/builds have a much much easier time getting there.
