Rance Quest:Equipment

Item Drop Rates
There are, roughly speaking, four different ways to acquire items in Rance Quest Magnum (excluding FrostBuy and one-off items). These are: green chests, red chests, post-battle, and magnum bonuses. They each obey their own mechanics on how they generate items, and what bonus point (BP) value to place on them. Magnum bonuses tend to be fixed, aside from Malgrid and a few exceptions, so those will be ignored here. Getting a drop short-circuits the rest of the logic, and percentages are mutually exclusive. For example, for chests, there is a 5% chance of getting a Rare Drop. If that happens, none of the other calculations will happen. Then there is a 15% chance of getting an Item. Then there is a 30% chance of getting a Special Item. (As opposed to 5 + 15 + 30 implying a 50% chance of getting a Weapon/Armor. The actual odds would be 56.525%).

Chests

 * 1) BP Calculation (start from 0)
 * 2) 50% chance of adding a random number from 1-3
 * 3) Add 1 if it is a red chest
 * 4) Add 1 if a party member has Improve Fortune
 * 5) Add 3 if this is a extra bonus point chest (last chest in Malgrid 1-6, Malgrid X)
 * 6) Add 2 if this is World 3
 * 7) Girl Scrolls
 * 8) If you have beaten The Third Army of Helman, guarantee Mill, Elenoa, and Karma's scrolls, in order
 * 9) If you have beaten Papal Inauguration Ceremony, guarantee Nozomi, Shitomone,and Wichita's scrolls, in order
 * 10) 75% chance of applying Tomato's preference skills (Weapon and Armor Lover, Special Item Lover, Item Lover) to force something from that respective group
 * 11) Certain types of chests get a "3 Bonus"  that adds a 10% likelihood to certain drops (more research needed, seems to apply to specific chests on specific quests, and also all chests in Malgrid X)
 * 12) (5 + Rare Chance Increase)% odds of getting a Rare Drop
 * 13) The Rare Chance Increase increases by 2 after opening each chest
 * 14) The Rare Chance Increase resets to 0 after getting a rare item
 * 15) 15 + "3 Bonus" chance of getting an Item
 * 16) 30 + "3 Bonus" chance of getting a Special Item
 * 17) Otherwise, get a Weapon/Armor with the specified BP value

Battle
There is a 50% chance of getting an item if all enemies in a red battle encounter have been defeated, or a 100% chance of getting an item if all enemies in a red battle encounter have been defeated and Tomato is in the party.
 * 1) BP Calculation (start from 0) (some increases may be illogical)
 * 2) 50% chance of adding a random number from 1-3
 * 3) Add 1 if it is a red chest
 * 4) Add 1 if a party member has Improve Fortune
 * 5) Add 3 if this is a forced rare item (last chest in Malgrid 1-6, Malgrid X)
 * 6) Add 2 if this is World 3
 * 7) 30% chance of getting an Item
 * 8) Otherwise, get a Weapon/Armor with the specified BP value

Magnum Bonus (unfixed)
This formula only applies to unfixed bonuses. Most bonuses are fixed. And some bonuses use a different formula.
 * 1) BP Calculation (start from 3)
 * 2) Add a random number from 1-5
 * 3) 20% chance of getting a Rare Drop
 * 4) 30% of getting a Special Item
 * 5) Otherwise, get a Weapon/Armor with the specified BP value

Auto-identification
Some Drops (Club, Girl Scrolls, Posters) are automatically identified. For the rest, the following formula is applied sequentially:
 * 1) 1/3 chance of auto-identification
 * 2) If BP is 0, then another 1/2 chance of auto-identification
 * 3) If a character has Treasure Appraisal, then another 2/3 chance of auto-identification
 * 4) If a character (Merim) has Treasure Appraisal+, then auto-identify

Rare Drops
Rules are applied sequentially, and immediately end once the rare drop's contents are set. If everything fails, then the above rules will act like the X% chance of a Rare Drop evaluated to false. Some things to note are that giving away certain items (Jewel, Forbidden Talent (weak), Lotion) will actually take away a Rare Drop from the player. For all items, they can only be dropped if they are not owned already.
 * 1) 2/3 chance of getting a Jewel
 * 2) 1/2 chance of getting a Sel scroll (but not on Runaway Ninja Fukiya)
 * 3) If Malgrid 3rd Stratum is cleared, 1/2 chance of getting a Karma scroll
 * 4) If Invade the Kalar Village has been cleared, and Days at the Macatt Bar has not been cleared, get a Lotion (A-C, in order)
 * 5) If Frostbuy has started selling Capture Rope, 1/3 chance of getting a Capture Rope
 * 6) 1/3 chance of getting a Forbidden Talent (weak)
 * 7) 1/5 chance of getting a Learning Device
 * 8) 1/5 chance of getting a Hanny Goods
 * 9) If a Capture Rope is owned,1/5 chance of getting a Strong Capture Rope
 * 10) If Yuzumi has been recruited, 1/3 chance of getting an Arquebus
 * 11) If an Aquebus is owned, 1/8 chance of getting a Modified Arquebus
 * 12) If an Ibeprofun EX Box is owned, 1/15 chance of getting a Ibeprofun EX+ Box
 * 13) If Kaito has been cleared
 * 14) 1/20 chance of getting a White Nurse's Outfit
 * 15) 1/20 chance of getting a Black Nurse's Outfit
 * 16) If on World 3:
 * 17) 1/15 chance of getting a Dewdrop Axe
 * 18) 1/15 chance of getting a Tarampi Suit
 * 19) 1/15 chance of getting a Maid Outfit
 * 20) Pick a random number from 1-4 (if already owned, continue to next step)
 * 21) Get a Shitomone scroll
 * 22) Get a Karma scroll
 * 23) Get a Wichita scroll
 * 24) Get a Nozomi scroll
 * 25) 1/3 chance of getting a Rare Item A, or any of the exceptions. The first drop that is not owned is the one that will be picked. There are implicit requirements for the Rare Item A drops that the requisite Quest has already been cleared for that character. Some unique items, such as Poison Dango, cannot be donated conventionally, but act as Rare Item A in this case.

 * 43) Leazas Red General Armor
 * 44) 1/500 chance of getting a Rare Item B (excluding Orgarhythm and Emperor's Armor). A random number from 1-11 is selected, and if that slot is already owned, then no item is gotten.
 * 45) Sacred Tree Armor
 * 46) Ulaanbaatar
 * 47) Champion
 * 48) Magic Minister
 * 49) Uruncel Blade
 * 50) Persiom

 * 56) If Tower of Babel has been completed, 1/5 chance of getting a random S-tier Special Item. The HP+ item has a rate of 3/13, while the rest have a rate of 1/13 (these add up to 100%)
 * 57) Otherwise, go back to the original drop calculation and progress to the next normal drop

Item ranking and bonuses
Weapons and armor all have an overall rank that goes from nothing to ⑤. For shop items this rank raises after buying an item and leaving, so on your next visit that longsword will suddenly have a ① after its name if you bought one. This rank increases the price of items by 50% per level and damage/defense by 5% per level, meaning that at rank ⑤ items will be 25% better but cost 250% more gold. Additionally, this rank affects all random drops you get during quests. So if the shop is selling a rank ⑤ longsword, ALL longswords you get later will have rank ⑤ too. For rare items the rank is equal to which world you found the item (confirmed till world 3). For example, if you find Hideo Sword at world 2 then you'll get Hideo Sword with rank ②. But it doesn't work with the first world, all rare items you get at the first world, have no rank.

For Magnum the rank goes up to ⑨. Also the increase of price and damage/defense is different. All percentages are calculated from base values at no rank.

Weapons, armor and some Special Items dropped from quests can have a random number of bonuses, denoted by the number on the lower left corner of the item icon. This number can be increased by fulfilling the bonus condition(s) in the quest. Note that this method only affects unidentified items. There are three types of bonus conditions, from top to bottom: collect a number of yellow spiky orbs, level up a number of times, win (not escape or time-out) a number of red spiky orb battles.

Generally, higher ranked items are found in quests with higher difficulty.

"Growth" attribute
Some weapons and armor have Growth (displayed as 成長率０％) or GrowthRare (成長率Ｒ０％) bonus on them. This allows them to increase their base stats the more you use them. Growth is capped at 1000% and GrowthRare at 3000% (?) (capped at 5000%). Equipments do not need to be rare to get growthrare.

2.082TADA: After completing quest #173 or #174 or #192 the rare chance to get GrowthRare bonus on regular equipments becomes enabled. (I got the first one on a Knuckle KAI in #174)

Weapons of C or CC rank get +5 to attack or/and magic for each 100% growth, B or BB rank - +10, and A, AA, S and SS rank weapons (and guns) get +20 to attack for each 100% growth. Attack or Magic must be present on item to get growth bonus.

Armor of C or CC rank gets +5 to physical and magical defense for each 100% growth up to a maximum of +50, B or BB rank armor gets +10 up to a maximum of +100, and, finally, armor of A or AA rank gets +20 to both stats for each 100% growth up to a maximum of +200.

For armors that have attack attribute for example Hell Set or Warrior Armor, the attack growth seems half of the physical and magical defense growth. (need confirmation) - Not true, armor's attack attribute will stay the same as its defense growth normally (T.Ha).

Growth is not working on characters that have too high level. If character got red message "Monsters are too weak" on experience distribution skill after battle, his weapon or armor will not gain any growth. This rule does not work on armor growth.

Example:

1. Rance lvl 51 is leveling on map with monsters level 43, and wearing a leather armor with level 39 requirement. It does not grow. After moving armor on Kanami who is level 40 (with a maximum of 40) it starts growing, although she does not get any experience due to hitting max level.

2. Rance lvl 52, wearing a sword that is also level 52 and leveling on a map with monster level 43 - item does not grow. On map level 47 item grows.

The growth may have connection with exp the equiped character receives, not the number of times the item is used (confirmed, you just have to equip the item). My Onoha equiped a maid girl monster 1%. The maid only healed once. Onoha didn't get to move even once. After one dungeon, the maid was 80%. ''- as for girl monster to growth, the girl monster must appear along with the character that's equipping it in combat. It doesn't need to act though.''

"Body boost" attribute
Displayed as 身体ブースト５％ or 身体ブースト１０％. Increases character's Attack, Defense, Magic and Magic resistance by 5% or 10%.

2.082TADA: After completing Malgreed 10th floor, the chance to get Boost 5-10% bonus on regular equipments becomes enabled.

"Efficient action" attribute
Displayed as 効率行動. Can be found only on some unique items (like Shizuka's Crystal Rod or Pastel's Queen' Cane). The same as skill with such name - there is a chance that skill won't use it's count when used.

"Invincible barrier destruction" attribute
Displayed as 無敵結界破壊. Can be found only on Rance's unique sword Chaos. Removes Majin's invincible barrier by damaging it once.

"Complete recovery" attribute
Displayed as 戦闘後完全回復. Can be found only on Ria's clothes. Fully recovers character HP after battle.

"Experience gained" attribute
Displayed as 取得経験値－６０％ or 取得経験値＋３０％. Negative value decreases the amount of experience character gains (can be found on Demon sword Chaos), positive value increases it (can be found on some clothes that can be use by Sparta or Civilian classes).

"Damage reduction" attribute
Displayed as 闇属性ＤＭ３０％減 (Dark element damage reduced by 30%) or 全ＤＭ２０％減 (All damage reduced by 20%).

"Reduce HP 20% after battle" attribute
Displayed as 戦闘後ＨＰ２割減. Can be found on unique armor Orgarizm. After battle character loses 20% of total HP. HP won't be reduced to 0 because of this skill.

"Assassination success UP" attribute
Displayed as 暗殺成功率ＵＰ. Can be found on unique weapon Beheading sword. Increases chances of successful assassination.

Special Items
Special Items will be destroyed when you unequip them. They usually give straight bonuses to stats and are useable by all character classes.

When a character is "reset" due to the curse, the Special Item will be "absorbed" by him. It is possible to absorb only 5 items this way, next time item will be compared to the 5 that were already absorbed and one with the lowest rank will be lost. Absorbed items can be exchanged with current item by the use of quest 107 (Alice Support Centre). There is a strange bug that make the item slot look empty after being exchanged, but the stat boost is still effective.

After updating to Magnum, Rance's Special Item will be absorbed with a random event when moving between maps.

Unique equipment
There can be only one piece of unique equipment in inventory. It is possible to upgrade all items by selling or donating them. After that they can be found at random treasure chest or gained from magnum bar reward with a random bonus and +1 for every time you have donated it.

Very important to note, that you can only find the donated/sold character unique items in the order they appear, so only donate/sell them 1 by 1 starting with items you want to upgrade first, because if you have donated/sold unique items above ones you want to find, for example Lia's clothes, you will always find Lia's clothes before you find any other character unique items, so don't donate them all at once, hoping to quickly find multiple replacements.

Tip: Not sure it's the best way and if it's worth doing, but if you really want to replace a specific unique, but having trouble to for a long time - only get rid of the one you want to replace, grab Tomato(with chest finding2) and Merim(with open luck) and run to Malgreed F6 B2 and grab the chests there and restart if you don't find anything good, that way I've found 3 versions of Lia's whip within a few minutes, but the bonuses depend on completeing high level quests, so ideally rush through F7-10 first, that way you should be able to find 10% stat boost and growth rare bonuses on uniques.

Leave out Merim once you find a good spot(I had a chest generated by Tomato that had a unique appear in the exactly same spot many times, for example) if you want to try for the +3 bonus or just remove characters with ID before opening a chest. Take Torako or Kenshin if you want to avoid encounters to save time.

List B

 * Stats of these equipments appear to be random, if you are lucky, you may get extra growth rare on some of them. The best way is use quest #199 and "quick save" trick. 2.082 TADA - I got MoM and Spear of terror from mimic fights (at least one of those fights were on map #80).
