[Vokrii] Spell Damage Formula

Good morning!

​

The purpose of this post is to learn about the formula used to determine Destruction Spell Damage, specifically how certain buffs add up, so that I can predict how much DPS my character will do before I sit down to roll my new character next week.

Relevant Mods are Vokrii, Andromeda, Imperious, Wintersun

​

Race is Altmer

Spell in question is Sparks (8 damage per second)

​

Assuming Destruction level 100:

+40% Destruction spell damage

(racial perk) Elven Supremecy - +10% Destruction

(Hermaeus Mora) Wrathful Dieties - +20% Destruction

Total = 70%

​

Amplify Destruction Enchant from gear - Assume +30%

​

The Atronach (Andromeda) - +25% Spell Magnitude

The Apprentice - +50% (assuming successful roll) Spell Magnitude

Sorcerer's Robes - +25% Spell Magnitude

Total = 100%

​

(Hermaeus Mora) A Studen't Tower - +50% Novice Spell Magnitude

​

Augmented Shock - +40% Shock Damage

Elemental Conflux - +20% Shock Damage

Total = 60%

​

I'm pretty sure that bonuses from different categories will multiply with each other but I'm unclear whether certain bonuses that seem to boost the same stat might also stack that way. Like, I'm pretty sure Enchants from gear are a different category than bonuses from perks.

​

Base Damage = 8

Variables can be:

d = Destruction= 70% = x1.7

e = Enchants = 30% = x1.3

m = Spell Magnitude = 100% = x2

n = Novice Spell = 50% = x1.5

s = Shock = 60% = x1.6

If I'm wrong about which bonuses stack additively, please identify new variables in the comments.

​

This is where I get stumped because I don't know enough to put the formula together myself. Can anyone help me out?

​

Thanks! :)
