Multiplicative mods are summed then applied

Quote:APeckenpaugh: "I haven't checked your math, but your logic is correct. In the current game, the way our math works is that multiplicative mods are summed in their entirety and then applied, such that if you received a 33% damage bonus to Unload, and then received a 25% damage bonus to Unload, you'd receive a [1+0.33+0.25=1.58] damage increase to Unload, NOT a [(1+0.33)*1.25=1.66] damage increase to Unload."

Interesting tidbit from the developers there.

I believe this was known at least one a case-by-case basis for most things. For example, the stacking mechanics of stat boosts. I've been assuming for a long time that most multiplicative effects are additive with each other.

This doesn't extend across bonus types, however. For example, if you receive a 33% increase in damage to Unload, and you cast that on a target taking 10% additional damage, the target would take 46.3% additional damage, not 43%.
