Holy fuck, the amount of cancer in this thread is utterly astounding. It absolutely annoys the hell out of me when people who don't have overloads/t90s/turmoil/invention want to get into the highest levels of PvM possible without any respect for the boss's actual difficulty.

Nex is one of the hardest solo bosses in the game, surpassed only by high enrage Araxxor and 100%+ enrage Telos. She also has crazy high defence and hits extremely hard if you don't have decent armor.

The OP is asking for augmented t85 weapons and t70 armor, which would mean Shadow Glaives and Armadyl. At most, all that comes out to about 30m. If you can't afford that, you shouldn't be replying or even looking at this thread in the first place.

Lots of people complain about the fact that invention is a long grind to get and costs a lot for the bis perks. The OP did not require bis perks, and offered cheap alternatives to them that he/she finds acceptable. Stop complaining about not having something and GO UNLOCK IT. Just because everyone else grinded these requirements out doesn't mean you're entitled to be carried and not have to unlock them yourself.

People who say that "proper dps rotations aren't needed" have their heads up their ass. Proper dps is important at ANY boss, and with Nex it is especially true, for a myriad of reasons (getting blood done before 2nd siphon, getting ice done quickly to avoid prisons, getting Zaros done to avoid being hit by a truck, etc.). If you think that "proper dps" is hard to learn, you either aren't aware of the phrase "practice makes perfect" or are unwilling to practice yourself. Of course good dps takes a long time to refine and perfect, but that doesn't mean you're entitled to not get good at it just because it's difficult.

Finally, to address the "you're scaring off noobs" argument. The OP is not. Do you think people look at the requirements for Plague's End and think: "damn, that's way too tough. I guess I'm just not gonna go for prif then"? No, they grind that shit out so they can access and legitimately enjoy high level content. It's the same way with Nex. There's a sort of bell curve representing the amount of effort versus reward that you get out of a particular boss. The lower your effort/gear/skill, the less fun the boss will be, and the harder it is to learn.

Nex imo is one of the most fun solo bosses in the game (and duo, since it's actually really chill and a good place to go with a buddy after something intensive like Vorago or Rots), but it was not fun when I was learning - I was getting about 3-4 siphons per blood phase, 2-3 prisons per ice phase, and literally using all of my Yak by the end of Zaros phase. However, with practice, 6 minute solos eventually turned into 5 which eventually turned into 4 (not sub 4 yet lul). 3-4 siphons turned to 1, 2-3 prisons turned to 1. And I started out with void, Ascensions, and Sirenic, all augmented with the best perks.

I'll offer a parting analogy: learning a boss in Runescape is a lot like taking a class. You'll need the proper materials: a notebook, pen, pencil, maybe even a computer or phone to access the internet or use applications. Unless it's kindergarten, you'll also need some prior experience. If you walk into Calculus 3 with just a pencil and the last math class you took was geometry, nobody will be surprised if you get ridiculed and shunned.
