I`ve been on a gridn to defeat Raxagon for a few hoursnow and I couldnt do it.
I wish there was more of a sense of progression like levelling up and so on to make things easier.
This game's strength progression is mostly tied to class/skills, and equipment
If your class has a strong single target skill I'd get that, and then otherwise you'd have to grind for better gear, retreating when you feel it is likely you'll lose all your loot
The items are RNG but generally you don't require rare gear to win fights
