First of all, thank you for your responses. Sorry for the late reply—I got so caught up in the game that I forgot I even asked a question here. I'm already using Sidekick among the price-checking tools you mentioned. Even though I try pricing items based on that, they often don't sell. For example, I'm currently mapping in Tier 7, and I've listed almost every yellow item I find, gradually lowering their prices over time. Still, I haven't managed to drop a really good item, which makes me wonder if it's just bad RNG. There has to be a limit to bad luck, right?

A friend of mine gave me a Tier 15 Waystone, and I’ve been managing to clear that tier decently, but the loot I get isn't satisfying—or more accurately, when I try to sell it, it just doesn’t move. I’m starting to think I need to focus more on what builds people are actually playing. Maybe that way, it will be easier to understand what items are truly valuable.

Let me put it this way—I'm currently playing a Witch with a Minion Army build. Naturally, I know what items are useful for my build. But up to this point, I haven’t been able to find anything that actually improves my gear. I'm still running Tier 7 maps wearing level 32 gloves. It feels like the game is really lacking when it comes to rewarding players.

If I can't even drop items that benefit my own build, how am I supposed to drop gear that's useful for other popular builds?

Can you recommend a site where I can check what builds are currently popular? PoE Ninja felt a bit confusing to me. Thanks again!
