Primordial Chasm is a challenging bonus dungeon in Shiren 5 that may be the closest experience to the classic, hardcore roguelike experience. All other daytime dungeons could be thought of as practice for this, the ultimate daytime dungeon, though it doesn't cover the full breadth of possibilities in Shiren 5 as it is daytime only. (This dungeon is the closest equivalent to the final dungeon in Shiren 1, Fay's Final Puzzle.) Nothing is pre-identified, and the item distribution is relatively wide even on early floors. You can't take items, Gitan, or allies into the dungeon, but you do keep items you have on hand if you win and you can request rescue up to 3 times if needed. The goal floor is initially 50 F but after first victory becomes 99 F and stays there permanently.

Gaining Access

After beating the Tower of Fortune, return to the blacksmith's shop in Hermit's Hermitage to unlock access to the Primordial Chasm. You'll get a short cutscene of an Ancient Mamel asking Shiren for help, after which you can enter the Primordial Chasm through a glowing pot in the blacksmith's shop. After first victory, you can also warp directly to the Primordial Chasm from the Sparrow Transport in Nekomaneki Village.

Unique Features

• The dungeon is daytime only.
• All items are unidentified by default.
• There is a wider distribution of items in general.
  • Unlike many dungeons, you can find a wide variety of items, including very dangerous items, on early floors.
  • Some items that are rarer in other dungeons seem to be more common in this dungeon.
• There are no wandering NPCs, but all three types of shops can be found.
• The difficulty ramp is harder/steeper than compared to the Tower of Fortune, but seems about the same as for many other bonus dungeons.

The Japanese wiki claims that a shop of some kind always appears on 10 F, 25 F, 50 F, and 75 F. This has not yet been confirmed in the English version.

Final Reward

The first time you beat the dungeon (by descending past 50 F), you get a cutscene of Shiren, Koppa, and the Ancient Mamel finding a portal. The Ancient Mamel thanks Shiren and Koppa giving them an Onigiri Shield, and goes through the portal back home to ancient times. Koppa then suggests it might be fun to go through the portal as well, but the god Reeva appears and states that they may not go through. (Didn't we defeat Reeva a few times already, so couldn't we force our way into the portal? Maybe Reeva was just giving us a small challenge then and is actually more powerful than he previously let on?) In any case, the heroes don't go through the portal and return home.

On subsequent victories, you get a cutscene in which Shiren and Koppa reach the end without the Ancient Mamel, and the portal is gone. As there is apparently nothing to do, Koppa says they should just head back, which is the end of the cutscene. There is no reward item for subsequent victories.

Farming Opportunities

This is one of the more difficult dungeons, and you can't take items in, so it's not a good location to try to deliberately farm out any specific items. However, because the item table is wider than in most dungeons, it might be possible to find something a bit rare on early floors and get lucky to find a way to escape out of the dungeon, or for swords and shields, you could tag them at a shopkeeper and hope to get them back from the Sentry at Hermit's Hermitage if/when you die, though cash is not particularly abundant in this dungeon. If there is in fact always a shop on 10 F, it might be relatively easy to find a good sword or shield before 10 F, sell everything else to the shopkeeper on 10 F, which would hopefully give you enough cash to tag the 1 sword or shield you want.

Strategies

There are no unique strategies needed for this dungeon, but you will need to be a very strong player to beat this dungeon. Some specific topics you will need to master:

• You'll need to know how to most efficiently identify items.
• You'll need to know how to maximize the value of monster houses, including when to create them and when to skip them.
• You'll need to know how to maximize the value shops, including them for price checks, for mass item identification, and especially knowing when and how to steal from them safely.
• You'll need to know all about runes and crafting great equipment on the fly.
• You should plan for what monsters you will face on upcoming floors.

See the Shiren 5 Strategies section for information on most of these topics. See the Monsters section of this page for information on what monsters appear at what depths of this dungeon.

If there is in fact always a shop of some kind on 10 F, 25 F, 50 F, and 75 F, you should definitely plan to take advantage of that.
