Formulas for damage and such

[Kythras]

I'm curious, did anyone figure out how skills and other factors influence the damage of spells and melee damage? With the code being open source it's probably not very hard to figure out

 

I would love to know how skills affect damage in a more accurate way than personal experience. Also useful would be to know how the ability strength of an item (as set in the scenario editor) affects the damage output of a spell.

 

Anyone know anything?

Combat.cpp is the major file for Windows here. Magically Apt I will have to research soon.

Your last sentence refers to wands? I will have to look that one up.

Right when it comes to hit something, but for damages it is done in SPECIALS.cpp (apparently needs some functions in there).

Quote:

It is checked in the function pc_record_type::statAdj() in PC.cpp which return the skill adjustement to be used in the formulas.

Click to reveal.. (explanation)

short pc_record_type::statAdj(short which)
{
short tr;

tr = skill_bonus[skills[which]]; //gets stat adjutment in the skill_bonus table (GLOBVAR.cpp) which correspond to the level in the which skill

if (which == 2) { //if checked stat is intelligence
if (traits[1] == TRUE) tr++; // if possess the Magically Apt. trait add one to tr
if (hasAbilEquip(99) < 16) tr++; //add one to tr if has one item equipped with ability 99 => this ability is inexistant ... Bug probably ...
}

if (which == 0) // if checked stat is strengh
if (traits[8] == TRUE) tr++; //if posses the Exceptional Strength, add one to tr

return tr;
}

The whole process of hitting/damaging monster is almost decoded, but i will have to finish mapping item abilities to be completely accurate.

I didn't looked into wands neither, but i think it also used the pc_cast() function.

Hope it helps,
Chokboyz

[Ishad Nha]

I drew up a list of the item abilities and put it in a spreadsheet: my list shows no item ability 99.

Line "if (hasAbilEquip(99) < 16)" would thus do nothing.

[Chokboyz]

You are right, i didn't find a 99 ability either. Seems like another bug in the code (i confirm your finding that demons does undead damages and vice versa).

Oddly, i can't find the same function (stat_adj()) in ormus' build (the declaration is here but can't find the function).

 

I finally complete the CONSTS.h file and put it here for anyone to use. Maybe you can confirm the values since you seems to have done the same

It is the only "stat_adj", thus you have a head without a body, "statAdj" seems to be the norm, thus declaration will need to be altered.

My notes came from the Editor help file, it should be interesting to see how that compares to the code. This will take me some time to compare.

 

I just ran the items properties through Word and Excel, I found a few possible problems:

#define Poision Protection 34 34 Poison Protection FALSE TRUE

#define Sleep Cloud 123 123 Sleep Field FALSE TRUE

#define Grawmold 156 156 Graymold FALSE TRUE

 

As for Word and Excel, a tab stop in Word equates to a new cell in Excel, here is an example of this at work:

 

Original text:

(here white space is represented by @)

#define@ITEM_MISSILE_RETURNING@170

#define@ITEM_MISSILE_LIGHTNING@171

#define@ITEM_MISSILE_EXPLODING@172

#define@ITEM_MISSILE_ACID@173

#define@ITEM_MISSILE_SLAY_UNDEAD@174

#define@ITEM_MISSILE_SLAY_DEMON@175

#define@ITEM_MISSILE_HEAL_TARGET@176

 

Change white spaces to tabs, here tabs are represented by tildes, ~

#define~ITEM_MISSILE_RETURNING~170

#define~ITEM_MISSILE_LIGHTNING~171

#define~ITEM_MISSILE_EXPLODING~172

#define~ITEM_MISSILE_ACID~173

#define~ITEM_MISSILE_SLAY_UNDEAD~174

#define~ITEM_MISSILE_SLAY_DEMON~175

#define~ITEM_MISSILE_HEAL_TARGET~176

 

Change text to Title Case, I first had to change it to lowercase to get this to work.

#Define~Item_Missile_Returning~170

#Define~Item_Missile_Lightning~171

#Define~Item_Missile_Exploding~172

#Define~Item_Missile_Acid~173

#Define~Item_Missile_Slay_Undead~174

#Define~Item_Missile_Slay_Demon~175

#Define~Item_Missile_Heal_Target~176

 

Delete "Item_Missile_"

Returning~170

Lightning~171

Exploding~172

Acid~173

Slay_Undead~174

Slay_Demon~175

Heal_Target~176

 

Now the data is in a format that can be used in Excel to compare it to my own notes. #Define is in a column by itself, so it can be safely ignored.

In Word, Ctrl + H is the shortcut for the Replace function. Check out the More and Special lists.

Traps: BoE Editor help file says that type 6 is "no trap after all".

 

My methods:

Use Gamedlog.rc and Gamestr.rc

Use the Editor help file

 

The monster and item properties seem okay.

 

[Chokboyz]

The typos have been fixed and SLEEP_CLOUD has been changed to SLEEP_FIELD to match description.

 

I did find the statAdj() function in the code (thanks) and the older stat_adj should indeed be removed (the item 99 bug is also present in statAdj ... what ability should replace this, skill ? will ?).

 

Thanks for cross-checking the values,

Chokboyz

[Chokboyz]

In this post, I will try, as asked, to describe what happens (code wise) when you attacks a monster (when a monster attacks you or another monster, it is quite different as some things are simplified and others not ...).

To do so, i will explicit the two fonctions used in the process pc_attack() in COMBAT.cpp and damage_monst() in SPECIALS.cpp. The original (windows) code is used for accuracy.

 

Before beginning, here are two things one should know :

• The minmax(a,b,c) function returns a if c<a ; b if c>b or c if he is in between (with a<. The function get_ran(c,a, returns a random number between a x c and b x c.
• The Bless/Curse level of a monster or a character is the same variable with positive value being blessed and negative value being cursed (the same is true with haste/slow, ...)

Here we go ...

1. Hitting a monster (pc_attack())
   • First if the adventurer is absent/dead/dust/stone/whatever_except_here_and_sound or if the adventurer is sleepy or paralysed, don't do a thing.
   • Then checks the weapon(s) equipped by the pc
   • Calculate the hit_adj (hit adjustement) following the formula

      

     hit_adj = (-5 * minmax(-8,8,AdventurerBlessLevel)) + 5 * minmax(-8,8,MonsterBlessLevel)- stat_adj(value_of_dexterity) * 5 + (Adventurer_encumberance) * 5;

      

     Here, the stat_adj is the "value_of_dexterity" index in the following array (begins at 0) : {-3,-3,-2,-1,0,0,1,1,1,2,2,2,3,3,3,3,4,4,4,5,5}

   • Calculate the dmg_adj (damage adjustement) following the formula

      

     dam_adj = minmax(-8,8,AdventurerBlessLevel) - minmax(-8,8,MonsterBlessLevel)+ stat_adj(value_of_strength);

      

     Here, the stat_adj is the "value_of_strength" index in the following array (begins at 0) : {-3,-3,-2,-1,0,0,1,1,1,2,2,2,3,3,3,3,4,4,4,5,5} , plus one if the character has the Exceptional Strength trait.

   • If the target is sleepy or paralysed, substract 80 to hit_adj and add 10 to dmg_adj.
   • If the attacker has an item with the skill ability equipped, add 5 * (item_level / 2 + 1); to hit_adj and item_level / 2 to dmg_adj.
   • If the attacker has an item with the giant strength ability equipped, add item_level * 2 to hit_adj and item_level to dmg_adj.
   • Negates sanctuary for the attacker
   • Then it depends of the weapon(s) equipped
     1. If weaponless, you punch. The hit roll is calculated following the formula :

        hit_roll = get_ran(1,0,100) + hit_adj - 20+5 * (adventurerWebsLevel / 3)

         

        The damage roll is calculated following the formula :

        dmg_roll= get_ran(1,1,4) + dam_adj;

         

        If the hit roll is less or equal to the "value_of_dexterity" index in the following array (size 51) : {20,30,40,45,50,55,60,65,69,73,77,81,84,87,90,92,94,96,97,98,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99} you hit and call the damage_monst() function with dmg_roll as parameter.

     2. You've got at least one weapon.

        It first get the type of weapon you wield.

         

        Then, the hit roll is calculated following the formula :

        hit_roll = get_ran(1,0,100) - 5 + hit_adj - 5 * weapon1_bonus + 5 * (adventurerWebsLevel / 3)

        If you wield a second weapon without having the ambidextrous trait, add 25 to hit_roll.

        If you are a slith wielding a pole weapon, substract 10 to hit_roll.

         

        The damage roll is then calculated following the formula :

        dmg_roll = get_ran(1,1,weapon1_level) + dam_adj + 2 + weapon1_bonus

        If the weapon has the weak weapon ability the damage roll becomes

        dmg_roll * (10 - weapon1.ability_strength) / 10

         

        If the hit roll is less or equal to the "value_of_weapon_skill" index in the following array (size 51) : {20,30,40,45,50,55,60,65,69,73,77,81,84,87,90,92,94,96,97,98,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99,99} you hit. Else you miss, play the animation and miss sound and goes on to C.

         

        Then it calculates special damage (spec_dam) depending of the weapon ability

        • For a flaming weapon, spec_dam = get_ran(WeaponAbilityLevel,1,6).
        • For a demon slayer weapon, spec_dam = 8 * WeaponAbilityLevel if the monster is a demon.
        • For a undead slayer weapon, spec_dam = 6 * WeaponAbilityLevel if the monster is an undead.
        • For a lizard slayer weapon, spec_dam = 5 * WeaponAbilityLevel if the monster is a reptile.
        • For a giant slayer weapon, spec_dam = 8 * WeaponAbilityLevel if the monster is a giant.
        • For a mage slayer weapon, spec_dam = 4 * WeaponAbilityLevel if the monster is a mage.
        • For a priest slayer weapon, spec_dam = 4 * WeaponAbilityLevel if the monster is a priest.
        • For a bug slayer weapon, spec_dam = 7 * WeaponAbilityLevel if the monster is a bug.
        • If it is a cause fear weapon, it reduces the morale of the monster by 10 * WeaponAbilityLevel if the monster doesn't absorb spell or is magic immuned.

          If magic resistant, it reduces the morale of the monster by 5 * WeaponAbilityLevel (no spec_dam).

           

          Then it checks if you assassinate. To assassinate, the level of the pc must be more or equal to the level of the monster minus 1, his skill in assassination must be more or equal to the level of the monster divided by 2 and the monster mustn't be a splitter (can't assassinate a splitter).

          Then if get_ran(1,0,100) < hit_chance[max(AdventurerAssassinationSkill - MonsterLevel),0)], where hit_chance is the same array as in A, you effectively assassinate and

          add the dmg_roll to spec_dmg.

           

          And finally it damages the monster by calling damage_monst() (see 2 below).

           

          After dealing damages, if the pc has poison on his weapon, the poison level (+2 if he has a poison augment item equipped) on his blade is added to the monster poison counter and the poison level on the blade is reduced.

          Then if the weapon is a poisoned weapon (the ability), it has 1 chance out of 2 to poison the monster with (WeaponAbilityLevel /2) poison level.

          If the weapon is an acid weapon (the ability), it has 1 chance out of 2 to put acid on the monster with (WeaponAbilityLevel /2) acid level.

          If the weapon is a soulsucker weapon (the ability), it has 1 chance out of 2 to heal the pc (WeaponAbilityLevel /2) health.

     3. You have a second weapon equipped.

        It does exactely the same thing a second time except :

        • No race slith adjustment for pole weapon equipped
        • The hit roll is calculated following the formula :

          hit_roll = get_ran(1,0,100) + hit_adj - 5 * weapon2_bonus + 5 * (adventurerWebsLevel / 3)

        • The damage roll is calculated following the formula :

          dmg_roll = get_ran(1,1,weapon2_level) + dam_adj - 1 + weapon2_bonus

        • There is no assassination, nor poison with the second weapon.
     4. It reduces poison on blades (once more), take 4 AP away and finally if the monster has martyr's shield (spell or ability) on and is not killed it damages the pc by the amount of damage done to the monster.
2. Damaging a monster (damage_monst())

    

   The parameters are dmg_roll (amount of damage) and spec_dmg (amount of special damage, i.e item ability, ...).

   • First if the monster is resistant to the type of damage, the dmg_roll is divided by 2 ; if it's immuned dmg_roll is reduced to 0.
   • Then if the monster absorb magic and the damage type is fire, magic or cold, add dmg_roll to monster's health and stop here.
   • If damage type is fire or cold, and if get_ran(1,0,20) <= MonsterLevel, then dmg_roll is divided by 2.
   • If damage type is magic, and if get_ran(1,0,24) <= MonsterLevel, then dmg_roll is divided by 2.
   • If the monster has the invulnerable ability (a.k.a Rentar-Ihrno in the code), then dmg_roll is divided by 10.
   • The Armor Roll of the monster is calculated following the formula :

     armor_roll = get_ran(1,0,(MonsterArmor * 5/4)) + MonsterLevel / 4;

     If the damage type is weapon (and only weapon ; undead and demons bypass this. Thanks Thuryl) substract armor_roll to dmg_roll.

   • Then if dmg_roll is greater than 0 (dmg_roll + spec_dmg) are deduced to the monster health. If dmg_roll is less or equal to 0, no damage is done and the function stop here (no special damage).
   • Then if it is a splitting monster, split it.
   • Updates the party damage statistic and make the monster hostile and active (a monster see you-like).
   • The splash animation is done and the monster is killed if it health is strictly lesser (<) then 0
   • If the monster is alive, it reduces its morale by 1 if damages done is between 1 and 5, 2 if 6 and 10, 3 if 10 and 20 or 5 if greater than 20.
   • Finally, if you damaged an innocent make the town hostile.

I may have overlooked something since it's a long list of thing, but everything essential should be here.

Unless I've missed something, you've overlooked the effect of the weapon skills: Edged Weapons, Bashing Weapons and Pole Weapons. Where do they factor in?

[Chokboyz]

This line got somehow squished in 1), it is now fixed.

Thanks,

Edit : was missing a line in C, with modified hit roll formula, fixed

hit_roll = get_ran(1,0,100) + hit_adj - 5 * weapon2_bonus + 5 * (adventurerWebsLevel / 3)

[Celtic Minstrel]

What? "Absorb spells" means that casting spells on the monster heals it?

 

I would have expected it to increase the monster's spell points (if it's a mage).

[Lilith]

Monsters with Absorb Spells are healed by magic, fire and cold damage, yeah. We've known that for a long time.

[Celtic Minstrel]

Well, I didn't know that, and it's contrary to what I would expect.

 

But that's okay, because I know it now[/i[.
