Alright, fellow Proxies, gather 'round! It's 2026, and I'm here to spill the beans on one of the most delightful (and slightly infuriating) scavenger hunts in New Eridu: collecting those elusive HIA Commemorative Coins in Lumina Square. You know the drill, right? The Sage, that mysterious feline figure, has once again decided their royal throne is a humble trash can, this time in the heart of Lumina Square. And just like in Sixth Street and Brant Street, they've scattered their shiny tokens all over the place for us to find. But here's the kicker – these coins have a serious sense of time. Think you can just waltz in during the morning and grab them all? Think again! They're on a strict schedule, appearing only at specific times of the day. So, ready your trusty Bangboo and let's dive into the neon-lit chaos of Lumina Square.

First things first, let's talk numbers and strategy. There are a total of 15 HIA Coins hiding in Lumina Square. But here's the good news: you only need to find eight of them to earn that sweet, sweet Officer Mewmew's Medal for this area. Phew! The coins can be found in any order, but their spawn is tied to the in-game time of day: Morning, Afternoon, Evening, and Midnight. If you're hunting and a coin just won't appear, don't panic! My tried-and-true method is to simply leave the area, pop into a nearby shop or building, and then return. This usually gives the game a little nudge and makes the next coin spawn. Magic? No, just good old Proxy troubleshooting.

Now, let's get to the juicy part: the locations! I've scoured every inch of this square (and maybe tripped over a few trash cans) to compile this list for you. Remember, for the 'Investigate' spots, the object needs to be sparkling before you can interact with it. No sparkle? No coin. It's that simple.

💡 Pro-Tips from a Seasoned Coin Hunter

  1. Time is Everything: Use that clock-skip function! Can't stress this enough. Stuck in Morning? Skip to Afternoon. It's your most powerful tool.

  2. The Reset Trick: If a coin listed for a specific time isn't there, leave the area completely. Enter a shop, like Coff Cafe or JC Pharmacy, then come back. This often fixes spawn issues.

  3. Sparkle Hunt: For investigation points, your eyes are your best asset. If it's not glittering, you're wasting your time. Come back later or after a reset.

  4. Eight is Enough: Remember, you only need eight. So if one coin is giving you a massive headache (looking at you, alleyway AC unit), just move on to the next one! There are plenty to choose from.

  5. Explore and Enjoy: Lumina Square is a vibrant place. While you're hunting for coins, take in the sights, listen to Tarshi's tunes, and maybe grab a noodle bowl. The hunt is part of the fun!

So there you have it, my comprehensive guide to conquering the Lumina Square HIA Coin challenge in 2026. It's a mix of patience, timing, and a little bit of that Proxy intuition. Now get out there, fill up that collection, and claim your medal from Officer Mewmew! Happy hunting, and may your trash cans always be fruitful! 🐱⚡
