If one of your minions gets a kill, the minion's IIR is added to yours and the total is used.

Also, spell damage calculations are a bit ambiguous. The way they are described in the thread, it seems like the spell damage multiplier for cold damage spell is (1 + spell damage % + elemental damage % + cold damage %). However, I heard that it's actually (1 + spell damage %) * (1 + elemental damage % + cold damage %). I mean, I heard that elemental and spell damage stack multiplicatively with each other, rather than additively. Both of those theories could be wrong, though. Also, passive and item spell/elemental damage bonuses stack additively, correct?

About spell damage, they stack addictively

Assuming those are all "increased" bonuses, yes.

"X% increased" and X% reduced" modifiers are additive. All applicable such modifiers are summed and applied together.

"X% more" and "X% less" are multiplicative.

Another example calculation
If you had a sword whose unmodified damage is 10-20, with the following modifiers:

50% increased physical damage on the weapon;
20% quality on the weapon;
5-10 added physical damage on the weapon;
6-9 added physical damage on a ring;
passive skills granting 30% increased sword damage;
a skill that does 40% increased damage and 30% less damage;

the calculation would would look like this:

Base damage: 10-20
Stage 1, on-weapon modifiers: (10-20 + 5-10) x (1 + 0.5 + 0.2) = 25.5-51
Stage 2, all other modifiers: (25.5-51 + 6-9) x (1 + 0.3 + 0.4) x 0.7 = 37-71
