Sengoku Rance:Parameters & Formulae

National stats

 * Cost (コスト) / Nation power (国力) - Cost is the total cost of all your commanders combined. Nation power is the sum of nation powers of the territories you control. The game will not allow you to hire a new captain who will put your total cost over the nation power or hire a number of troops that will increase a commander's cost such that your total cost will exceed your national power, although the plot may force a commander to join who will make your cost exceed your national power. If your total cost exceeds your nation power, you will receive half as much income from the territories under your control every turn.


 * Satisfaction (満足度) - When Rance achieves various objectives in the game, his satisfaction increases. Satisfaction can be used to trigger various beneficial events. See Sengoku Rance:Satisfaction bonuses for more information on the bonuses.


 * Gold (金) - Gold is the monetary standard of the land. You gain gold from lands under your control, events in the game and some of your unit's skills. Gold can be used for increasing a commander's maximum troops size or replenishing dead troops, it can also be used for several events within the storyline.


 * Score (得点) - The base score for the first game is 60 points. Every turn you lose one point. For every objective you achieve, you gain a certain number of points. Don't worry about the score on your first time playing through it; you are expected to get a score of 0. On subsequent playthroughs you can set the game to a higher difficulty, and you'll start off with more points depending on the difficulty. These points are used for buying bonuses for your second and subsequent playthroughs and only your highest score counts. See Sengoku Rance:Second Game Bonuses for the bonuses you can buy.

Personal stats

 * Name
 * Relationship - has two components:
 * Posture (red-hate, orange-normal, blue-trust, pink-love)
 * Progress (the smiley faces)
 * HP - Only used in commander/dungeon battles.
 * Level / Level Limit - the current level and the maximum level for this character. A character's level limit cannot be changed in game. Character level can be increased by:
 * as a reward option for increasing the relationship with the character.
 * by giving the character a Happiness Pokkuru (see Sengoku Rance:Items).
 * when completing the last level of a dungeon (for the first time for that dungeon), every captain gains a level (even if they were not used in the dungeon)
 * by special events. In particular Ogawa Kentarou has an amazing level up ability in most game routes.
 * Note: Your level only affects dungeon/commander battles (and greatly reduces enemy damage if yours is higher [Rance/Kentarou can go to 99]). It doesn't influence army battles, outside of the damage done by attack where the commander personally attacks (e.g. Commander Charge).
 * Job - The commander may have different job type than his fellow troop soldiers. The job of the captain is only important in dungeon/commander battles
 * Skills

Summary table
Different troop types with the same stats will work out differently. The troop type bonus for each of the four battle parameters is ranked in the manual from A+ to C.

Note that various costs may be affected by other factors such as items or satisfaction bonuses.


 * Attack = Base Attack + ATK * (1 + Buff Modifier) * 10
 * Defense = Base Defense + DEF * (1 + Buff Modifier) * 8
 * Magic Attack = Base Intelligence + INT * (1 + Buff Modifier) * 10
 * Magic Defense = INT * (1 + Buff Modifier) * 7


 * Max troop size is based on difficulty and the number of provinces controlled. Vassaled provinces are not counted. The base value is then multiplied by each unit's troop ratio.


 * Recruit cost goes up by 20 when troop size is 500~999. Recruit cost goes up by 40 more (base + 60) when troop size is 1000~?.
 * The attack power of new troops goes down with increased numbers.


 * Damage (Without Item Modifier) = {[Adjusted Troop Size * (Attack - Defense)%] * Skill Modifier} * Battlefield Effect
 * The number within square brackets caps at the actual troop size.

Randomized skill algorithm
Some skills, such as assassinate or whirlwind shot, have the ability to annihilate an enemy commander (without reducing their troop count) with a random probability. These skills are: The success/failure of these skills is determined using the following algorithm:
 * Assassinate
 * Assassinate 2
 * Commander snipe
 * Whirlwind shot
 * Aim and shoot

probability = 0%

if (Commander snipe) probability = 45% if (Assassinate) probability = 45% if (Assassinate 2) probability = 50% if (Whirlwind shot) probability = 45% if (Aim and shoot) probability = 40% //The skill that gives this buff is not obtainable through normal means if (attacker has concentration buff) probability += concentration * 10%

if (defender has assassination guard) probability -= 10% if (troop battle) { if (defender's troops * 2 < attacker's troops) probability += 5% if (defender's troops > attacker's troops) probability -= 10% if (defender's troops > attacker's troops + 1000) probability -= 10% }

if (commander battle) if (attacker's level < defender's level) probability = 0% if(attack has assassination skill + AND defender has no actions) probability = 100% if(defender isn't important AND probability > random(1-100)) ATTACK SUCCEEDS else ATTACK FAILS

The random number number is determined by the nth value in a list of 400 predefined random values, where n is a global variable that increments by 1 every time the list is accessed. When n reaches 401 it is reset back to 0 and the random numbers start to repeat.
