Hello my fellow Lightning wielding, teleport spamming Sorcerers. I have a few questions regarding gearing for Tower/leaderboard pushing that only you guys can help me with. TLDR if you want to skip the rant, I'm trying to push Tower, currently 135(125 2:33min) and have hit a hard wall and looking for gearing advice. Link below for what i'm running(Mekuna's BL for Skill/paragon allocation). More information getting spammed now. Thank you ahead of time for taking the time to read this and respond. <3

I'm new to ARPG's, but I get the gist of it. I love the game and wish there was more endgame, but since all we have is the pit/tower, I've begun trying to push it. I'm on 135 and it's finally getting hard. I can get through the trash relatively easy, with the occasional me getting smacked/one shot. But I seem to not to have enough damage to kill the boss in time. This started slowing down in 130, but I pulled that off with a few seconds to spare.

This means it's obviously a gearing issue. I know there's some things I can change in my gearing, but It's hard to find any good information out there. I've worshipped Mekunas BL video, but I'd love some input on more minmax. Some more Info about my set up, feel free to nitpick as much as you want and I'm super open to any tips, help and information.

• Helm and Weapon are both indesctructible for the Transfigure, thus why it's not on the planner.
• My weapon I swap between the one on in the planner and El'Druin with +7 All Skills/+45% All Damage. I much prefer the Weapon over the mythic. I know I lose the CD reduction from El'Druin, but I'm pretty good at Hydra uptime and that helps with my Ice Armor CD.
• Occasionally I swap off Raiment for Tyreals, but have no idea if that's helpful. On paper seems to have more DR, but I lost a good chunk of dmg that's on my Raiment.
• I always use Igni/Mot in Helm, but I swap the chest rune from Vex to Que for the Druid Earth Warden shield sometimes.
• I have that Mythic Seal that allows you to have the 5 set with only have 4 set charms on. All 4 charms are Ancestral +3 Shock(no luck on the +4 yet). The 5th slot is a random Charm with +3 Shock/97 Stats. My Unique charm is Godslayers whenever possible, but since 130 I've just permanently have Endurant Faith on. Even on the trash packs, I'll get one shot way too much if I'm not using it. IDK if that's me being bad, or the norm for you guys too?
• My Glyph levels are all exactly 125. I know Glyph levels are important, but I doubt that's why I can't kill? Maybe it is. IDK.
• I run Fire Shield instead of Fire Familiars while pushing. Since i'm not worried about speed, IDC about the Overpower/TP'ing from Familiars. Fire Shield I just spam when I'm hurt. I also use Fire Shield/Ice Armor as Enchanments at time too. IDK if worth, but seems to help me survive. Would love your input on the matter.
• I'm Thinking of Static Blizz node instead of the Vuln from Blizz. Since Double Affix on Winterglass applies Vuln. Unsure if worth?
• I have 100% uptime on Unstable and it ends around 220 stacks on average if I had to estimate. Can go much higher on trash depending on how fast i'm going, never ends under 200. So CDR isn't an issue with UC.
• I gem one Resistance in each jewelry slot to keep main three even. Poison, Lightning and Fire, since those seem to be the culprits in one shotting me. All are at roughly 6200

Stats with the planner set up:

• 2,963 Intellect
• (out of combat)480k Toughness(36k HP) with Overwhelming Currents weapon. 520k(39k HP) with El'Druins. 723k(34k HP) with El'Druins/Tyreals. 1.6m toughness in combat. 4.5m with Ice Armor up. 5.2m with El'Druins in combat
• 76.6% Crit chance out of combat. 88.8% in combat.
• 4k Crit Damage. This drops to 2.9k if I equip El'Druins.
• 57.8% Attack speed out of combat. 87.9 in combat(once again, no idea what's giving me so much in combat.)
• 181% Movement speed out of combat. 210% in combat(I have no idea what's giving me movement speed in combat)

Things I've been RELIGIOUSLY hard farming:

• Esu's, Winterglass and Stormhorn OH. I spend almost all my keys on Grigoire for OH, Spend Husks on Belial for Astaroth(I despise Escalating) The best I've been able to get is currently in use in the planner
• Gloves started as a Blue 1 or 2 GA. Prob spent the rest of my yearly luck at the Cube with it.
• I know I need legs really bad. IDK why I've never noticed how bad they were until last night. Currently trying to replace.

As mentioned, I appreciate all the help! I'm just trying to push leaderboards for the first time and figured I'd learn from the best.
