Lvl 25? Do you use mods?
31 gold or 500, lvl 1 is lvl 1.
The reason this purge seemed more difficult was…

This purge no matter the lvl can be devastating. Imagine that if this will happen with a lvl 10 purge consider many thralls dead. The agro is so high, the confusion is big and even if lvl 1 npcs can easily die in masses with gas, still it’s not a purge to handle easily.
So make sure to give your own distance for personal defense with just one thrall…

I am sorry for your loss, but sometimes these experiences are only making us better.

In challenges that i want to defend purges alone i fix hallways to control the number of npcs i have to deal with. If you have only a thrall, set it guarding behind you and attack nothing further to 5 meters.
Use the thrall to get a breath and heal and then go in front again.
Shields are life savers in these situations.
Have fun exile
