Primordial Chasm is a challenging bonus dungeon in Shiren 5 that may be the closest experience to the classic, hardcore roguelike experience. (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 enter Primordial Chasm directly from the Sparrow Transport in Nekomaneki Village.

Unique Features

• The dungeon is daytime only.
• All items are unidentified by default.
• There is a wide distribution of items, even on early floors.
• All three types of shops appear.
• There are no characters other than the shopkeepers.
• Monster difficulty ramp is steeper than Tower of Fortune, but is about in line with other dungeons where you cannot take items in.

Shops are guaranteed to appear on 10 F, 25 F, 50 F, and 75 F. They can also appear on other floors.

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

Primordial Chasm is a difficult dungeon, so it is not a good location to farm out any specific items. However, rare items do appear more often here, and you can hope to get lucky and find a way to escape. For swords and shields, you can tag them at a shopkeeper (there is always one on 10 F) so you can get them back from the Sentry at Hermit's Hermitage if you die.

Strategy

The general Dungeon Tips apply here. A few topics to pay attention to in particular:

• Ways to identify items, including price checks and mass identification
• Ways to steal from shops
• Using Mixers to add Runes to your equipment

Mixers appear on 8-10 F, 31-33 F, 50-51 F and finally 70-71 F. Plan to stay on these floors for as long as you can, so you can get all your mixing done.

Floor 10 deserves a special mention, since it has Mixers, a guaranteed shop, and Kumonigiri which can drop Onigiri, enabling your extended stay. If you can't do mass identification yet, you should price check each of your items, test them using a Mixer, and name your remaining items based on what you've learned. Watch out for Pop Tanks, as they can destroy shop items from a distance.

Mudkin and Swordsmen appear on 12 F. Be especially careful on this floor as these monsters can cause permanent damage to your equipment. Only fight a Swordsman directly if there's a wall behind you, with no monster in between. Remember you can un-equip your sword and/or shield before fighting a Mudkin.

Boy Carts appear on 19-20 F, Cross Carts on 28-29 F. If you have a Dodger Pot, use it on these floors and farm up at least 300 arrows.

There are guaranteed shops on 10, 25, 50 and 75 F. On these floors and the floors preceding them, it is worth checking every tile for traps before you walk on them, so you don't get caught by a Floor Warp Trap or Pit Trap. This also applies to the Mixer floors.

Once you are down to the last 10 or 20 floors, start making your way to the exit quickly instead of full exploring every floor.
