Would greatly appreciate advice for GR150
Hello, sorry for the massive wall of text, TLDR at the end but I might as well include any context and info I can think of in case it's relevant (and in case anyone feels like reading a novel). I am a relatively unskilled D3 player with a dream. I would love to clear GR150 just once in my life because I think that would be cool. But the step up from 146 to 147 feels so discouragingly massive. I really struggled with 137-139 as well and cleared my 139 with 0.6 seconds to spare, so I kind of thought I was doomed. But thanks to what I believe was mainly good RNG I basically breezed through the 140s so far. And now it feels like I need the best of RNG to even stand a chance. I got really close on one attempt but unfortunately I got Tethrys and I can not kill her in less than 3-5 business days due to her not spawning minions and liking to hang out right outside of my damage zone and dancing away when I move towards her.
I am playing nova necro with Trag'oul and Guardian's Jeopardy following icyveins/leaderboard build. All my items are augmented ancients except crafted primal offhand and non-ancient convention because I am not having much success getting an ancient with even decent rolls for it. I am using Scoundrel with 25k dex. I basically only deal damage when my convention syncs up with either his crit field, an oculus ring zone, or the damage potion zone from altar. My altar is maxed. Inventory lists my stats as 77 STR/DEX, 35,040 INT, 8987 Vitality, 10,634,284 Damage, 279,009,088 Toughness, 6,152,826 Recovery. Can provide specifics about any other stats on request but including everything would make a really long list.
Up until maybe 145 I have felt virtually invincible but lacking in damage. Currently I feel lacking in both survivability and damage. I feel like I need to dash around a lot in order not to die, but I only deal damage when I am able to stand still. Unless there is a secret trick to casting siphon blood while moving that I am not aware of. I have had decent success with dragging elite packs into groups of trash and essentially kiting them between trash hordes until they die, as well as grouping elite groups together. I feel like neither of these strategies are working out on 147, as they take so long to die that kiting feels impossible because scoundrel likes to stun them so they can't follow me and sometimes trash packs are just too few and far between. And I can no longer fight multiple elite packs at once because I take too much damage to be able to stand still and deal damage.
I have read on the internet which is known to never provide false information that pylons spawn based on how many enemies you kill or what % per map or something like that, so I do my best to kill everything I am physically able to but I still get at most 2 pylons per rift unless I am super lucky, and it feels like I mostly get speed and channeling, both of which are virtually useless for my damage output. I feel like the rift basically only has a chance of being possible if my first pylon is a conduit and there are multiple elites in the area so I can get many orbs and many kills which gives more pylons, and at least one other pylon basically needs to be strength, ideally I'd love a str pylon right before the guardian. But that kind of luck is very rare :') And atp I'm not sure how much of this is skill issue and how much of it is RNG issue. I am not able to grind for hours and hours due to chronic wrist pain which is aggravated by gaming. I am going to visit my grandmother for the entirety of next week and I am worried about not having time to finish 150 before season's end (and I really doubt I will want to try again next season knowing how much time and effort it has taken me this time).
TLDR: nova necro with Trag'oul and Guardian's Jeopardy, 77 STR/DEX, 35,040 INT, 8987 Vitality, 10,634,284 Damage, 279,009,088 Toughness, 6,152,826 Recovery, GR147 is really stubborn, not sure what my best options for advancing are, any advice is appreciated. Please feel free to ask follow-up questions etc.
