Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Are stat bonuses multiplicative or additive?

For example, if I have a character wielding a pair of fire wands, has 2 points in "dual-wielding"(+10% damage), one point in "aerotheurge"(+10% vs magic shields) and one point in "pyrokinetic"(+5% damage on fire attacks), will her wand attacks against magic shields deal 125% of normal damage, or 127%?
