Mage/Dark Wizard Improvements for nol?

Throw me a build for nol pls. I'm current using this trift monster build but sometimes I still got one shot with 91k ehp in boss. Why nol is so hard (at least for me).

You probably get oneshot by the lightning strike, which I've seen oneshotting people with very tanky builds. Versus the parasite, avoid the "void spray" from the void thing in the middle of the room. That also oneshots about anyone.

Avoid those mechanics and you should be fine.

 

I died even before the lightning starts, and every nol attempt always ended up with only another mage or a warrior have to solo the whole fight and eventually failed to, or only me survive and got killed in seconds by 20+ high dmg mobs chasing me around. One time I even have been one-shot right at the start of the fight.

 

That is weird. 91k eHP, no agi, is way above what you need for NoL.

I've done NoL many times, even on 40k eHP builds.

It's highly unlikely that you " just get oneshot at the start of the fight", without bugs or something. Try to balance powders around having at least a positive Air Defence. If you have 2 Fire VI on all armor, you can add 1 Air V to them to reach this.

Pick these buffs, priority in order, based on tankiness/sustain being your main issue as a Mage:

1st:

Ophanim I (Water Damage = Heal, Agility = more tankiness)
Throne I (more spam Heal due to mSteal)
Cherubim I (Walk Speed is pretty nice)

2nd:

Anti II(100 Strength is ridiculously good for builds with low base Strength, 9k Poison becomes high with Courage with Time Rift)
Ophanim II (Agility, Water Damage for better Heal)
Throne II (Damage, even more Mana sustain for if you REALLY mess up and need to spam heal 8 times)

3rd:

Cherubim III (!!!) (This is one of the best buffs as it gives tankiness AND damage for builds that have low Strength/Dexterity/Agility)
Seraphim III (Dexterity, mRegen, Spell Damage)
Any other buff than Ophanim III

!NEVER EVER! pick Ophanim III if you're not a dedicated tank/healer. 10k Health is not worth taking extra damage from your teammates.

If you really want, add me ingame (Arthexis) and we can run NoL together sometimes.
