Effect	Gain a chance to find gems while foraging. Has a 10% chance to consume an earth rune.

Root Digging adds a chance to find gems by 0.02% per foraging action. The first Root Digging buff adds a tiny chance to uncover gems depending on the base foraging time.

Root Digging can be brewed as a potion using cooking alchemy. Potion level strengths range from 1 to 4. There is a 10% chance that an earth rune will be consumed per foraging action.

As a scroll, this enchantment can be applied to a Hatchet or the Lumberjack Set (also known as the Foraging Set). Enchantment strengths range from 1 to the maximum number of slots on the desired gear.

Formula

The chance to find a random gem per action is calculated using this formula:

$GemChance={\frac {baseTime*2+rootDigging*100}{500000}}\times 100\%$

Without the Root Digging enchantment, no gems will be discovered while foraging.
