Is multi-shock additive or multiplicative?
Does the stormweaver node Strike Twice, which allows shock to be applied twice, add the shock value up additively, or multiply it together?
In PoE1, sources of damage taken added together. If an enemy was intimidated (10% inc damage taken) and had a 10% shock on them, they would get 20% damage taken, not 21% (1.1 x 1.1)
Is it the same for poe2 and double shock?

As far as anyone's found, it's additive. I think we'd know if it was multiplicative because people have gotten to 70+% per shock and if it was doing 3x damage instead of 1.5x damage with two shocks, people would have noticed.
Anything "increased" is additive. That is still true in PoE2. Shock is increased damage taken and therefore additive with other sources. That includes multiple shock stacks and also other debuffs that increase damage taken in some form, such as withered.
