What's the easiest way to get iridium ores? : r/StardewValley
If you want a consistant and relatively low investment way to get around 30, maybe 40 ores per day, you can slay purple slimes. They have a fairly high chance of dropping iridium ore (even on the first floors), and a small chance of dropping an iridium bar. It's even more worth it if you have the slime charmer ring, which unlocks after you have
