Perilous Rocks is a bonus dungeon in Shiren 5 with a higher rate of monster houses, including "pop-up" monster houses. You can't take items, Gitan, or allies into the dungeon, nor can you request rescue, but you keep the items if you win. The dungeon is daytime only and the initial goal floor is 50 F. After the first victory, the goal floor becomes 99 F and stays there permanently.

Gaining Access

This dungeon can be accessed from the Dungeon Center in Nekomaneki Village. Access is not restricted; you can play as soon as you can reach the Dungeon Center.

Unique Features

• Monster houses are more common than normal, and especially "pop-up" or "surprise" monster houses.
• Shops are more common than normal.
• Item distribution differs but it's hard to be specific:
  • You can apparently find the full variety of items in this dungeon, though not uniformly spread across all the floors.
  • Earlier floors tend to have less expensive and less harmful items.
• The dungeon is daytime only.

Final Reward

Every time you beat this dungeon (either version), you get a Worthy Shield, the level 8 form of the Shoddy Plank, which isn't particularly useful.

Farming Opportunities

Perilous Rocks is a difficult dungeon and escape items are scarce. However, items are very abundant in this dungeon, so you will find more rare items than usual. Swords and shields can be tagged, while some items (such as Angel Seed and Upgrade Pot) can be turned into a rune on a tagged piece of equipment via a Mixer.

If you synthesize with everything you find along the way, you will end up with a massive build. This can be a good way to obtain equipment with many upgrade points and runes.

Strategy

Like with other dungeons where you cannot take items in, many tips related to beating this dungeon can be found in Dungeon Tips.

This dungeon is very generous with items, due to the higher rate of monster houses and shops.

Mixers appear on many floors, and (as usual) try to merge all your items together before you leave these floors. In this dungeon, mixers often appear together with Mudkins, which can damage your equipment. Be careful while moving on these floors, and consider equipping a shield only so you can remove it if a Mudkin ends up next to you. Floors 7, 29 and 30 are opportunities to use Mixers without having to worry about Mudkins / Muddys. Be careful when trying to mix on 48-51F: a Mixergon might in fact be a Eagle Tengu, in which case your first item will be lost. On these floors, test out a Mixergon by throwing an item that doesn't mix (such as a Wood Arrow) and seeing if it swallows the arrow, and use the remaining 3 slots for mixing

. Maximizing monster houses: Never fight in the middle of the room, but retreat into a hallway. Use Pinning Staff to escape, use Cloning Staff to distract, use a Confusion Scroll if you need the entire room disabled for a few turns. If at all possible, avoid walking on any tile that you don't 100% know is untrapped. Note that the hallway entrances to all rooms including monster houses are never trapped to begin with. Swing your sword over every tile to check for traps, which is especially useful in small monster houses. It is debateable if you should use Steady Shield or Unmoving rune, since it is very helpful to be able to use a Warp Grass or Pinning Staff when in trouble without having to remove your shield first. Make sure not to step on the trap that turns all items into monsters, at least not until you've despoiled everything you want from the room. And lastly, learn to skip monster houses when you have virtually everything you want already, as beyond a certain point of wealth, the upside of risking a monster house becomes less and less worth it, esp. as you get deeper and the danger increases. Sometimes the best thing to do is to pin your way to the exit as fast as possible.

Shops appear often in this dungeon, and it is important to maximize them. Price check and name every item, and do a mass identification if you can. Look out for opportunities and reasons to steal from a shop.

This dungeon has a high frequency of "pop-up" or surprise monster houses. A room marked as a surprise monster house has a chance of popping up every time you take a step in the room, and there is no way to know it in advance. (For some theories on how these are triggered, see the comment.) However, you can still prepare for them. Warp Grass and Hide Pots are both good prep items. Keep both a Pinning Staff and Swap Staff to help you escape the room as quickly as possible if a monster house pops up while you're in the middle. Walk in a straight line every time you enter a room lets you pin out most easily. It's also useful to keep at least one Confusion Scroll on hand if possible. Confusion lasts much longer than Slumber, and the monsters don't "wake" from Confusion hasted. Fear Scrolls and Fixer Scrolls aren't bad but only work on your immediate neighbors rather than the entire room. And of course, Swift Grass and Invincible Grass are definitely useful emergency items. It's always a good idea to keep at least one Heal Pot on hand if you can. Of course, when a monster house first pops up, immediately stop and check what monsters you're dealing with (and don't forget that tiles you walked over already may now have traps on them). If there are particularly dangerous monsters (e.g. monsters that can put you to sleep by hitting you, monsters that can inflict bad status ailments by throwing things at you, monsters that can yank you to their location and surround you with other monsters), this might be an excellent time to pin completely out the room and a fair ways down a hallway if you still have an open line of site to do so, or to use a Hide Pot or Warp Grass if you don't have a direct line of site for escape via Pinning Staff.
