I just completed the rest of the hex members 1st try in less than an hour , like it's so brain dead i thought i was getting a bug. Asked 5 of my friends to tested it out and they killed the apex either 1st or 2nd time with this build, which they were struggling to get their 1st solo completetion before this build. I'll show it here as well, hope that helps anyone who wanted to give it a go.

Please keep in mind that the builds I'm showing below are just my preference, you don't have to 100% follow them. This build will focus on mainly surviability which I did struggle a bit on my 1st completetion, and this build is certainly Not for Early Game!!!! Please don't get angry at me for showing a build that you can't achieved in a very short pierod of time. The apex tank content was designed to be challenging and it requires a good understanding of the mods and gameplay. The main goal here is to help as much as possible for the completetion and if that works for you it will absolutely made my day ><!

There are things you want to focus and it will MAKE YOUR LIFE EASIER !!!!!!

Frame shown : No Forma Nyx Prime (my Cyte09 Mag Trin Volt Excalibur has at least 2-4 formas, my Nyx is the weakest which is perfect to show how shit I am hell yea)

Archon Shard: Tao Azure shard x3 : health x2 ,Armor x1

Subsumed Ability: Dispensary (Protea)

Focus: Madurai (Vazirin works too if u prefer the protective sling)

Aura: Corrosive Projection (I prefer Brief Despite, Energy Siphon /Physique/Steel Charge are also best for Auras! )

Companian: Wyrm Prime

HEALTH ,AMOR, DAMAGE REDUCTION : You want DAMAGE REDUCTION to move around if you lose all your sheild and during rolling guard cool down! More health and amor = more dmg reduction! ( Thank you Karmana giving me a heads-up with inaros health build, the apex is joke to Inaros) YES I AM VERY AWARE SHEILD GATING IS A THING (love it and use it in almost all my builds) I DID MY FIRST COMPLETETION WITH CYTE-09 PURE FULL SHEILD GATE BUILD , WITH NO HEALTH NO ARMOR NO DAMAGE REDUCTION NO MAX ARMOR STRIP AND I WANT AN ALTERNATIVE BUILD WHICH WORKS ON MY OTHER FRAME. Arcane Blessing will give you more max health, and with Protea's Dispensary will max it out very quickly.

The Important Mods Quick Thinking + Hunter Adernaline + Rolling Guard: Quick thinking will drain energy when u take leathal damage, with high max health you can take advantage of Hunter Adernaline (or Rage) for energy in return. Quick Thinking is such a life saver lets you get away with apex's BS macanics 90% of the time. Rolling Guard to let you get immune to all dmg type. ( I also added Adaptation and Aviator to get extra damage reduction to not get 1 shot to death. Energy Nexus in case you ran out of energy to cast Dispensary or your other abilities. Better be safe than Sorry) Flow/ Equalibrium is optional if you don't want to use Energy Nexus . You could use Acane Energize for energy regen but it's just not that good for the apex even with Dispensary.

The Helminth Ability Dispensary : This will synergize with all the mods and arcane for the build. To let you always have energy to proc Quick Thinking. When you take leathal damage you lose both health and energy , you can replenish both quickly with Dispensary. Make sure you spam it in apex phase 1 and 2 to keep orb flow sufficient. Arcane Energize is optional for energy regen , however it's just not as efficent as Dispensary plus it wasted a slot. I invest heavily on energy flow to stay alive because I hate being send to the backroom when i die and Steven point at me with a flipflop saying 'Failure'

Good quality of life: Arcane Nullifier to negate most of the magnetic proc from the apex tank, Arcane Fortifier on your pistol will give you overguard when u use pistol on eximus, phase 1 and 2 with all the eximus spawning should give the overguard you need to deal with the apex tank. Nira's Hatrated not only gives you health, the set bonus for extra 100% slam damage is amazing because we are going to using heavy slam a lot. Aviator to let you take less damage when you are shooting the weakspot on top of the apex. Madurai Focus School to give you Void Strike, you can deal even more slam damage in 8 seconds. The shorter it takes to kill apex the less risk you take. Wyrm Prime's Negate and all the shield regen mods will increase your surviability.

Melee Weapon choice: Magistar Incarnon or Sampotes, they are just too godly for this apex fight. Sampotes will need to keep a short distance for the waves to damage the tank, direct hit on apex tank has No damage >[]< !

This is my Latron Prime with Incarnon above, you can also use weapons you prefer (suggestions from feedback: kuva hek/ Torid Incarnon)

The epitaph to get overguard and slow + prime the enemies. Melee choice I pick Sampotes, I took both rivens off so my friends use the build with no rivens.

Here's my drifter loadout in case you would like to know ;)

Thesse are my build for Trinity, Mag and Excalibur. Trinity is so easy she does not need Dispensary, once you remove the overguard you can cast ablilities for energy + life pulse. Excalibur Umbra by far the easiest for no reason I even took off rolling guard. Mag can abuse all shield regen just remember to maintain your energy flow and you are all set!

If you have any good suggestion and builds that works very well please show some love and share to other tennos too. I know many MANY player actually hated this content and even with end game gears and loadouts can't complete the H-09 Apex fight. That is also why I make this build to help my friends out so they can have their fav hex memeber glyphs >w< !!!
