Hand of Fate. Part 2: Despair

I hope the author won't be offended if I give a small hint: the ability to traverse the desert is related to the hero's stats - two specific stats are needed, and then it's all good. To be honest, I wasn't the one who figured it out; the author gave me a hint.
But after crossing the desert, you'll encounter a problem: without Chaos and Dark Magic, it will be impossible to deal with the Hellspawn...
Good luck - the map is truly magnificent!

Thank you :)
It's not impossible; it will just take longer. I suggested this option as the fastest one (thanks to the "Deadly Cold" spell).
I won't be offended ;)
Moreover, I'll give another hint below:
Here are some verses:

In the desert of weeping sands
Greenheim's beast found its lair
Shining from the sky is that form
Beneath it, the Tear of the Goddess awaits

That hour will be terrible
When you take someone else's item
But only one path is true
In the beast's thigh, a myth will be found

-The highlighted words hint at where to find the Tear ;)

In the cave beneath the pyramid's tomb
There is an artifact that generates unprecedented power
The Trident, kept in the grave
A madman is he who touches this wonder

-The highlighted words hint at where to find the artifact ;)

He who drives the doomed into the footsteps of death,
He who gains the patronage of the Goddess,
He will be sacred in the desert of weeping sands.
And he will also receive my blessing.

-The highlighted words hint at which skills need to be upgraded ;)
