Hi there!
It is a very dangerous place for a person of your level, many with levels higher than yours, have died in that place.
The risk is very high, however, if you still want to go, I recommend using flask with snake poison over the cauldron to weaken.
Regarding the prey, you probably need defense, however I recommend that you enter without having activated any and as required, activate either defense or attack, the loot in this case will not be very useful compared to the other two options.
The recommended equipment is:
Head: gnome helmet or dwarven helmet
Chest: dwarven armor
Legs: dwarven legs
Boots: pair of dreamwalker
Shield: shoulder plate
Neck: garlic necklace
In addition to this I recommend you be careful with Cobra Vizier
(I hope you tell me how did you go, good luck)
