Sengoku Rance:Dungeons

In checklist order

 * Orochi's Cave 大蛇の穴
 * Tomb of Sekimei セキメイの墓

General Info
Every dungeon consists of a number of levels. The moment you enter and complete at least one level, then one level of the dungeon will be permanently cleared. For example, if you enter a six-level dungeon, clear two levels, and exit, you will enter the dungeon at level 2; if you cleared five levels, you will still enter the dungeon at level 2. However, note that if you fail to properly exit the dungeon (i.e. clear the first five but fail on the sixth against the boss), you will not get a check point at level 2. Instead, you will have to start at level 1 again (or your last floor checkpoint). Since you get a random item (usually Ogre Bones for the item shop) every time you clear a level, the most efficient method to farm a dungeon is to clear all levels except the last in one action, exit, and do it again next turn, repeating the procedure until you're able to start at the last level. You will also get one random affection boosting item/healing item/motivation paper everytime you succesfully exit a dungeon (on top of the medicine sake/seirogan that you get for the first few incomplete runs through that dungeon). The last level of the dungeon includes at least one boss and is unaffected by the "Dungeon Scout" skill. Clearing the last level gives you a one-time level up for all commanders in your general roster and a treasure, which is usually pre-determined (unless you chose it as a second-game bonus). If you already have it, the game will randomly give you another treasure; if you have all possible dungeon-clear items already, you will get a random stat 2 Textbook (which has no restrictions) or Good Medicine (also a consolation prize for failing a dungeon).. The random treasure is set from the moment the game is started (so reloading saves will not work) and will differ from game to game.

The very best (but potentially the most tedious) method of farming ogre bones requires you to intentionally fail the last floor of a dungeon by dying/running out of action points. When you leave a dungeon this way, you will not clear any floor levels permanently (ie. if you clear the first 4 floors but die on the 5th, you will not get to start on the 2nd floor next time as you did not manually choose the exit the dungeon). This method ensures that you will never exhaust the dungeons down to the boss floor like the previously suggested method of farming ogre bones. However, be advised that there are 4 dangers of doing it this way:

1) No bonus item when you retreat from the dungeon involuntarily

Suggestion: If you're farming SenriQ Cups or Kanou Scrolls you would actually be better off doing one floor of a dungeon, exiting manually, and then restarting if you don't get it. There's nothing more agonizing then going down 10+ floors of a tough dungeon (because you wanted to farm the maximum number of ogre bones as well in the same action) only to find out you got a JAWS screen/Expert's drum/Seirogan for the 10th time in a row.

2) Taking forever to lose on the bottom floor

Suggestion: During most commander-only battles the game will allow you to cycle in your entire commander roster until everyone is either dead or out of action points (those who have less than full action points or 0HP from a previous dungeon crawl will not be switched in). Try to make sure you exhaust a lot of actions points/characters on the way down or you'll have to "stand by" for awhile on the last floor.

3) Limited runs per turn

Suggestion: You'll most likely run out of action points and/or HP for a second run on the same turn. Wait until the next turn and perform other actions in the meantime.

4) Not enough commanders to defend invasions afterwards

Suggestion: Any commander that dies while dungeon crawling is disabled from taking further action for the rest of the turn (name will be marked off). Do your best to exhaust your action points rather than your HP on the bottom floor.

Longest dungeons: Tokugawa Buried Treasure (13 floors), Yomotsu Hirasaka aka Road to Hades (18 floors) or Orochi's Dungeon (20 + 1 floors).

 * Location: Himeji 姫路
 * Floors: 5
 * Requires: Kanami to discover
 * Bonus Loot: Various (3) +Sat items (does not require Kanami)
 * Note: other name Tora no Ana. Incidentally, the "joke" here is a play on words for "Torana", the ceremonial gate located in front of many Buddhist shrines and monasteries. Torana is the gate, "Tora no Ana" means "Tiger Cave". In other words, Rance stole Kanami's thunder and named the dungeon after a very dumb pun. Poor girl can't get a break.

SM Dungeon ＳＭ迷宮

 * Floors: 10
 * Requires: Okita Nozomi to unlock
 * Bonus Loot: 2 Extra Level-ups for Rance, if the final party got Okita, you got +3 level for Rance plus one item at level 10.
 * Boss Info: The Boss is a Mazone, a female alien from the old (late 70's) anime series Space Pirate Captain Harlock. This one however is garbed in bondage gear and nailed into the ground by her hair, quite immobilized.
 * This boss has a self-heal that heals for just over 300 HP. This move also has a percentage chance of failing (around 75% in my experience).
 * Your main strategy should be: attack non-stop until she's dead. Simple? It should be. The only way you can lose is if you're tagging along pure weaklings and she just keeps getting them lucky heals.

Yomotsu Hirasaka 黄泉平坂

 * Location: Izumo
 * Floors: 18 (18th level - 7777 HP Boss battle)
 * Unlike Sekimei and Orochi, the boss battle is part of the dungeon crawl. This means you do not get action fans restored before the battle.
 * The boss always uses the same attack, which hits the entire party.
 * Requires: Enter Uesugi Kenshin's Route OR Unlock Orochi's Cave (SEE Natori in the Sengoku Rance:Walkthrough section) OR recruit Sakamoto Ryoma and click the purple ??? event in which Ryoma talks about removing Mori Motonari's curse. (In 1.04 there does not seem to be any requirement when you conquer Izumo before the Honnou Temple event. However if you do not search for it before the Honnou Temple event, the option to seach for it will disappear, and will not appear even if you unlock Orochi's Cave and talk to Natori about the Emperor's Sword. Unconfirmed if the disappearance of the search option is due to the route I entered.)
 * Bonus Loot:
 * Mori Motonari's curse is lifted (Kill Daidara after a purple event with Sakamoto Ryoma)
 * Emperor's Sword (After 8th floor? (Requires Orochi Dungeon to be Open to Aquire as well as a ??? purple event with Natori after its open.) Requirements unclear. Emperor ring is not required.)
 * CG #102 (Dungeon Clear)

Orochi's Cave 大蛇の穴

 * Location: Yamatai
 * Floors: 20 + 1 (Boss battle with Orochi or with Xavier in Uesugi Kenshin route)
 * Requires:
 * Tamagushi Fuuka (Up until Step #7 of her Character Clear, but choose the 2nd option)
 * Natori to unlock


 * Alternatively, it is unlocked towards the end of the Uesugi Kenshin route


 * Boss Info: Orochi
 * Before the battle, all action fans are restored. Wounded characters are not healed, however.
 * Orochi's regular attacks pierce, hitting the unit behind his target.
 * Orochi also has a devastating attack that hits your entire team for absurdly massive damage. This will kill most characters. The theory is that it can only use it once per fight. Therefore it is advised to put out the weakest units first - they will be the human shields for your main characters. Orochi seems more likely to use this around a party of high level chracters or Rance.
 * Orochi's Minions are extremely annoying on their own. They have a fire attack and a single target healing spell that they can cast on themselves, other minions or the Orochi itself.
 * None of Orochi's attacks are magic, but his minions' attacks apparently are. If they happen to focus on her, Rizna's immunity can prevent significant damage.

Tomb of Sekimei セキメイの墓

 * Location: Saitama
 * Floors: 7+1 (Normal Difficulty) 12+1 (1 Star+) ''Boss battle with Sekimei)
 * Requires: Enter and proceed in Nanjo Ran's Route
 * Bonus Loot: Win the Boss Battle and you've beaten Nanjo Ran's Route! The Loot is the unlocking of the Nanjo Ran 2nd game bonus.
 * Boss Info: Sekimei is a huge adorning Golden spiked armor.
 * Before the battle, all action fans are restored. Wounded characters are not healed, however.
 * His size grants him extensive reach, making all his attacks long range
 * His single attack will remove one random buff from his target
 * While his HP is low (compared to the other Bosses) and his attack power is only average, all his other stats are way over the top. With his defense and intelligence, you'll find your units dealing half of what they normally do, and with his speed, he might have 2-3 turns before all but your fastest units get theirs.
