New-ish player looking for advice (Power Level 162)

Hey! I’m a fairly new-ish Minecraft Dungeons player and I’m currently around Power Level 162.

I’ve mostly been grinding The Tower, and it’s helped me level up a lot, but I’m not sure if that’s the best thing to keep doing or if I should start focusing on something else.

I’m looking for advice on:

What weapons, armor, and artifacts are actually worth keeping?

Which enchantments are considered the best?

What’s worth buying from merchants, and what’s a waste of emeralds or gold?

Are there any DLCs that are really worth getting?

What should I be farming at this stage of the game?

Any solo builds or tips you wish you knew when you were around my level?

I’ve been enjoying the game a lot and would love to hear what more experienced players recommend.

Thanks!
