Played a bit of javazon this ladder, wasnt convinced even with decent gear. Quite probably didnt take it far enough. If I had to again, I guess I would spec for dual fire/psn pen (titans revenge, gelebs greed, amazon helm with -15 -15, assassin set belt with -15 -15, shield RW for crazy fire dmg/pen or 4xPoison rw for +2block and psn pen) and give it a go. I dont think procs are the way to go, or at least not convinced at all.
For MMzon, since it has great damage i suggest trying out the Eviscerator (+10% base block) sword and just MO +magic/phys dmg on it. You DO lose some damage, and need like 1k dex or so, but you gain a near-free 75% block, giving you a huge survivability (meh def + perf block + HIGH RANGE + SUPERB HP). Definitely makes her tankier.
Currently playing spearzon and enjoying it, lv120, though not tried curare yet (about to). Just started using Arkaine's Valor on my spearzon and with the incredibly high %tcd on spearzon it gives SO MUCH VIT that I feel paragon is not that much needed anymore.
Solid options for weapons are I feel either craft / Titanomachia (Xis) in eth spear / 6x poison rune. (right now ive got a strong craft)
I do feel however very sad about the 6x earth rune recipe for spears. It has amazingly good damage rolls + nice leech for a weapon RW... BUT it doesnt make it indestructible like the regular 6x Earth RW for other weaps. Results in poor damage cause no jewels, no other runes (Jahs), no gems (skulls + paragon), and most of all NO ETH WEAPON. Any decent craft will equal or outdo it sadly. 6x Poison rune suffers from the same fate but has 60% psn pierce and good psn base, its for curare so its alright if the base phys is not super competitive, and even so its decent.
I guess a full-poison oriented build with segnitia would work, but unsure about how efficient that would be. To be tested I guess. Please give me your input regarding this (curare or not, and which weapon to use ? ), hesitating a lot right now
edit : I forgot to mention, since I dont use curare yet, im playing fulltime GH. No leech, very poor farming, but amazing damage at least. Will probably change once I use pounce
