Welcome to the final village of this game, the Underground Stream Village. This village does not have much. There is a shop straight up at the top left which can contain very decent items. Outside of that, there is only backstory to be found here, so I won't describe the town layout. Feel welcome to chat with the Characters at your leisure. Once you are ready to move forward, you will be heading up Table Mountain some more before facing the "final trials" which are the last few floors.
Since there is not much to say about this town, I want to describe in detail a prime grinding strategy that you may employ at your leisure now. Remember when I said going back to towns would reset the items in shops? Well that holds true here. This town produces one of the most famous grinding spots. Again, I want to stress that it is absolutely not necessary to bother doing this to succeed. Doing this can however be of great assistance to you. The general premise is simple, you just need to find and activate a pitfall trap on the very next floor, floor 22. Doing so will return you to this town. The benefits of doing this is that items will actually re-spawn on floor 22 for whatever reason when you do this. So you can constantly look for new loot and then go shopping at the shop so long as you can keep this up. The Mecharoid enemy spawns on floor 22. If you find one, you can lure it around the various rooms until it makes a pitfall trap for you to utilize. If you happen to have a Bufu's Cleaver meld on your weapon, you can constantly make Mecharoid meat from the enemies to make your own pitfalls.
Be mindful will doing this grind that it is a major hunger drain. Riceballs are semi frequent at the shop but not guaranteed. They are also harder to find on the upper floors so only do this a few times so long as you have the food to do so. But you can infinitely do this strategy at your leisure, and like I said the shop actually provides some decent items so it can be worthwhile. This method is also how you can grind up gear easily with a strengthening jar, but that's not important to worry about for this guide so I won't go into more details. For more on this, see: Stream Village Shopping Spree.
When you are prepared, begin your final ascent. It is going to be 8 straight floors of Shiren challenge before the final boss of Table Mountain.
