As I understand it, some skills utilize additive damage bonuses, while others are based on multiplicative damage bonuses.

Examples of additive bonuses are for instance Anatomy (+20%) and Tactics (+50%). The bonuses are added together into +70%, and then added to the weapon damage so that it would deal 170% of base damage.

Examples of multiplicative bonuses are for instance Discordance (I'm not sure if it is). So in this case you would take the 170% damage from above and multiply by 1.25, giving 212.5% of base damage. If it was an additive bonus the total damage would be 195% of base damage.

So based on the skills and special effects below, could you please run through them and point out which ones are additive and which ones are multiplicative Luthius ? And did I miss any?
