Quoting the docs (documentation):
► Show Spoiler
On the first level, there are two types of monsters. Sand Maggot Eggs will spawn young Ghost Worms which are untargetable and will use a deadly poison attack, while the Eggs will prevent your heal. In other words, you just have to run like crazy and avoid dying, and get high poison resistances, because you cannot use potions.
In other words: this is an uberlevel. You are not supposed to do it on your current level. Do it once you are level 120 and have appropriate gear to do it. Just skip the maggot lair and go into the claw viper temple. Both the staff and the amu will drop there.
You should check out the documentation:
https://docs.median-xl.com/There are all useful cube recipes listed and all uberlevels with a little strategic guide. You can also find some gear there, which you may want to make (uniques or runewords) depending on your build. The docs are your best friend!
