Elemental damage in elona+ 1.90

Elemental damage with references to 1.90's code for limits and formulas

TargetResistLevel = Target.ResistVal(AtkElem) / 50;

if (TargetResistLevel < 3)
   CalculatedDamage = CalculatedDamage * 150 / limit(TargetResistLevel * 50 + 50, 40, 150);
else
   CalculatedDamage = CalculatedDamage * 100 / (TargetResistLevel * 50 + 50);

CalculatedDamage = CalculatedDamage * 100 / (Target.ResistVal(Magic) / 2 + 50);


Translates into:  ((damage * 100) / (element_resistance + 50)) * (100 / (magic resist / 2 + 50))



For lvl 100+ enemies: Default Resists: 300 element + 200 magic (bosses have more magic resist, npc resists can vary, undead are usually weak to fire, etc.)

Elemental scar: -150 to fire/ice/lightning at capped effect
nightmare: -150 to the rest (except magic) at capped effect

oil   fire damage *7/4 or 1.75x
      pv/dv  * 13/10   or 1.3x

wince  damage *11/10 or 1.1x (will be 1.2x in 1.94+ according to change-logs)

wet   fire damage /2  or .5x
      cold damage *7/4 or 1.75x
      lightning   *3/2  or 1.5x



Effective damage multipliers (higher is more damage, sorted from weakest to strongest)

.2857 * .666667 = .19047   ( element damage )
.4    * .666667 = .266667  ( magic damage )
.5    * .666667 = .33333   ( element + scar/nightmare damage)
.5    * .666667 * 1.5 = .5     ( Lightning + scar + wet damage)
.5    * .666667 * 1.75= .583   ( fire + scar + oil damage)
.5    * .666667 * 1.75= .583   ( cold + scar + wet damage)
.5    * .666667 * 1.75 * 1.1 = .6413   ( fire + wince + scar + oil damage)

1.1 / 1.3 = .84625  ( physical damage + wince + oil ) (this won't effect the fire damage, as it uses unmodified base damage as it's reference)

in 1.94+

.5    * .666667 * 1.75 * 1.2= .7  ( fire + wince + scar + oil damage)
1.3 / 1.3 = .923  ( physical damage + wince + oil ) (this won't effect the fire damage, as it uses unmodified base damage as it's reference)


For magic spells (assuming race feat from itzpalt's gem):
    Meteor > fireball = iceball > lightning ball > eclipse > magic ball
    Bubble ignores resistance but is the weakest, only use it for overly resistant enemies, or to wet 'em.
    Combines element enchants work for fire/ice, sound/mind, nerve/poison, with the second element capping at +150% bonus damage with 750 enchant power.

    Recommended strategy: bubble then fireball, elemental scar as needed. Assuming you have the combines fire/cold enchant.
