What is the best way to handle lots of weapons with lots of variables changed by lots of items

Unity Engine

I’m just looking for a general idea of how to set it up in unity and if I should use scriptable objects or not

How would I go about cleanly having all item data in a script together with all the weapon data?

This is the flow chart of how I would do it right now with current knowledge
(Weapon Script) Weapon raw damage and effect ----> (Calculation script) Adds multipliers and effect ----> (Weapon Script) Executes attack with newly calculated effects and damage

How would I go about calculating multipliers based on equipped items without using a lot of if statements

Item1 2% dmg (equipped)
item2 4% dmg
item3 7% dmg (equipped)

Can this be done without doing this

if (item1Equipped == true)
{
damageMultiplier = damageMultiplier + item1.damageMultiplier
}
if (Item2Equipped == true)
{
[...]
}

I’m sure there is a way smarter, more elegant, and modular solution. I just don’t know what it is, maybe something with a foreach and an array of equipped items or something

Kind of in the same vein as the last question but how would I avoid lots of if statements, when for example the damage type changes and the code need to use a different damage multiplier

if (fireDamageType == true)
{
swordAttack.finalDamage = swordAttack.damage * fireDamageMultiplier
}
else if (sharpDamageType == true)
{
swordAttack.finalDamage = swordAttack.damage * sharpDamageMultiplier
}
//Etc

Any advice would be greatly appreciated

ScriptableObjects are a great way to encapsulate the different parts of this.

Iteratively building up the system you want is going to be the magic sauce. Do NOT try to get it all working at once. Start with a weapon you wield and a damage applier that takes that weapon and hits an enemy.

Only once that is working add more: perhaps a weapon buff system that the damage applier also consults to adjust the damage.

After that perhaps the damage applier talks to damage taker on the enemy, and then that damage taker might be able to have armor or defensive buffs.
