I am a bit confused about how Savagery exactly works. I read a lot of stuff on the forum (and others), with sometimes outdated posts. Let’s take an example and correct me when I am wrong.
 Let’s consider a fully maxed Savagery line (so with maxed Tenacity of the Boar/Storm Touched skill modifiers, and maxed Might of the Bear transmuter). I attack with a 2H melee weapon, being at full charge. My damage would be (numbers are from Grim Calc, doesn’t matter if they are not 100% correct):
 Base Damage of the Weapon x1.5 (150% Weapon Damage component), including any additional damages on the weapon (and possibly from buffs like Deadly momentum or Brute Force if applicable? see point 3 below)
 37 Lightning Damage (with a 20% chance of multiplying it by 3.55 from Storm touched – see point 2 below)
 42 Bleeding Damage
 80142 Electrocute Damage
These last 3 (or 4?) are then multiply by the charge bonus (1.15 in that case), then by the 15% from the transmuter, and then all of them are multiply by their respective %Damage bonus from Equipment/Passives/Devotion/Spirit or Cunning, which are all additives. And then, a possible multiplier for a critical hit is taken into account. And… hopefully I am not forgetting anything! So in this scenario, lots of things are in fact multiplicative, which would be good!

What is confusing me a bit is the exact role of the skill modifiers. When searching for how damage conversion works, I read that skill modifiers kick in before transmuter and damage conversion, which I translate as being multiplicative with other modifiers (hope what I am writing is making sense to you…). This would mean that they are in fact very powerfull!

Also, I am not sure when exactly Brute Force (for example) is taken into account. Included in the 150% WD or apart from it?

For completeness, what about WPS? If Feral Hunger triggers, when do the 130% WD and the 82 Bleeding Damage come into the equation?
Sorry for the complex(es) question(s), but it is not easy to find accurate and uptodate information about that. Thanks to any of you for inputs on the subject!
