Mythstone Boost Question

From what I have read and experienced, it would seem the mythstone (or crystal, but I haven’t tested that) boost gives 100% more (quantity) mythstones, but I am curious if someone has extensively tested, or heard from an actual game dev, whether we are getting 100% more quantity, rarity, or both. I am also curious if the 100% is additive or multiplicative (if I’m getting 200% drops (2x) before the boost, do I get 300% (3x) or 100% more than 200% (4x)?)

Does anyone have any good data or dev responses on these questions?

Just Quantity, and it simply doubles the chance that a Mythstone will drop. Getting more than one boost increases the amount of kills that the boost lasts for.
