Damage conversion, Glacial Cascade, Avatar of Fire

Hello, everyone.

I have read some article about damage conversion, how it is applied, and how it is calculated, but I still have some question in my mind.

I will take the case of Glacial Cascade to explain my problem (a skill that deals Cold damage as well as Physical damage).
Note : the numbers shown are not correct, and there are no modifiers like %SpellDmg or %Elemental.

0 - Context :
- Skill : Glacial Cascade
- Support Gem 1 : Cold to Fire
- Support Gem 2 : Physical to Lightning
- Keystone : Avatar of Fire

1 - Basics :
Imagine that Glacial Cascade deal the following damages :
- Physiscal (100%) : 100
- Cold (100%) : 100

2 - Cold to Fire support gem :
Now I link Glacial Cascade with a first support gem, Cold to Fire :
- Physical (100%) : 100
- Cold (50% remaining) : 50
- Fire (50% from cold) : 50

3 - Physical to Lightning support gem :
Now I link Glacial Cascage with a second support gem, Physical to Lightning :
- Physical (50% remaining) : 50 (A)
- Cold (50% remaining) : 50 (B)
- Fire (50% from cold) : 50 (C)
- Lighning (50% from physical) : 50 (D)
=> Total = 50 (pDmg) + 150 (eDmg) = 200

4 - Avatar of Fire keystone :
Now comes the tricky part, I take the Avatar of Fire keystone :
- Fire : 50 (from A) + 50 (from B) + 50 (from C) + 50 (from D) * 1/2 (Avatar of Fire)
=> Total = 50 + 50 + 50 + 25 = 175 (Fire eDmg)

Note : 25 of Lightning damages are lost due to Avatar of Fire.

Is my calculation correct or am I missing something?

If you are willing to answer this post but are not sure of yourself, please don't post, it will only confuse me and the people passing by.

Thank you for reading.

EDIT: add the lost Lightning damages.

Well, replace all that shit by flameblast , and here you go.

Here's how it works (ignoring the +10% from CTF and PTL):

Glacial Cascade:

100 physical
100 cold

Cold to fire:

100 physical
50 cold
50 fire

Physical to lightning

50 physical
50 lightning
50 cold
50 fire

Avatar of fire

(25 physical convert to fire)
(25 lightning convert to fire)
(25 cold convert to fire)
+ 50 fire

= 125 fire


You don't actually gain anything from physical to lightning in this case. You could get rid of it and the damage would be the same.

EDIT: you would actually gain an additional 2.5 damage from physical to lightning and another 5 from cold to fire (assuming level 1) because of their x% of physical/cold as added lightning/fire property so this isn't entirely accurate, but that's the gist of it.

Wow, that would be bad. You sure of this?

I am sure of this, I've used avatar of fire with glacial cascade myself in the past. It's much more effective to use cold to fire + added fire damage because then you get

50 cold (= 25 fire)
100 physical (= 50 fire)
50 + 20 fire (= 70)

for ~145, or 150 if we're being pedantic (from lv1 ctf's +10% cold as fire).

Thank you.

I guess I'll have to test this out.
I like this Glacial Cascade skill and I really want to get the best out of it.

Avatar of Fire + Cold to Fire gem = 100% cold to fire conversion +x% of cold as extra fire (x depends on the lvl of cold to fire gem lets say 10% for our example)


In your glacial cascade case : 100 cold + 100 physical will become : 160fire

You do realise that the numbers talked here are hypothetical, and the actual physical dmg of glacial cascade is half of cold more or less. Added fire dmg is a big waste of a gem slot if you are going for conversions in glacial cascade

Rustic sash + added fire is one of the largest damage boosts you can do with avatar of fire for a physical spell.

GC is not pure physical spell and its physical part is much less than the elemental one. Also, i suggest to learn how AoF and conversions work
