Block Drop Calculation

With the release of the v0.11 Dwarven Mines update most of the block drop increases have been condensed into multiple fortune stats for each relevant activity, greatly simplifying how the drop chances are calculated.

Mining
$$averageAmount = baseAmount*baseDropMultiplier*(1+miningFortune/100)+additiveBonus $$

Where:
 * $$baseAmount$$ is the amount of drops received without any bonuses.
 * $$baseDropMultiplier$$ includes bonuses that increase multiplicatively with one another (Mining Fiesta, Skymall's 5x Titanium).
 * $$miningFortune$$ is your total mining fortune bonus, including ore-specific bonuses (see Mining Fortune).
 * $$additiveBonus$$ is comprised of bonuses that are unaffected by the base drop amount or by (Fallen Star, Mithraic Reforge).

Example
Mining Titanium Ore with Mining Fiesta and 5x Titanium active while near a Fallen Star, with 300.

$$2*2*5*(1+300/100)+2=82$$

Farming
$$averageAmount = baseAmount*(1+farmingFortune/100)$$

For a list of modifiers that affect crop drops, see Farming Fortune.

Foraging
$$averageAmount = baseAmount*(1+foragingFortune/100)$$

For a list of modifiers that affect log drops, see Foraging Fortune.
