In general if enemies are more than one level above you then you shouldn’t be there. It should be possible to find something at your level throughout the act.
Also, don’t forget to abuse the hell out of consumables. The crafting system is overcomplicated and a lot of the equipment you can make is worthless, but consumables are not. You can easily use the honey in various spots in the area to make charm arrows and grenades which basically mean you just need to get the magic armor off enemies and then they’re on your team until you’re ready to kill them. Except for Source Orbs nothing in the game is too rare to use at the first good opportunity.
