The Prospector kit is an experience-boosting set, purchasable from Prospector Percy's Nugget Shop in the Motherlode Mine. Pieces of the kit are purchased using golden nuggets obtained randomly through mining pay-dirt. The set costs 180 nuggets in total.
Despite having two lights attached to it, the Prospector Helmet does not act as a light source.
Obtaining[edit | edit source]
|Item||XP Boost||Cost (in)||Sells for (in)||Boost per nugget|
(% per )
|Complete set||+2.5 %||180||144||0.014|
When obtaining this particular set, the most efficient method for gaining a higher amount of boosted xp over time is to start by purchasing the more expensive items first. This can be calculated by adding up the xp boosts one would get when buying the items in either order. For both calculations, the variable x is the amount of pay-dirt it takes to receive a nugget, on average about 36.5. Nuggets are received from pay-dirt at a constant rate of 2.74%, so x can be substituted with 1 for easy calculation. y is the amount of mining xp each pay-dirt awards the player, which is also a constant and can be substituted for 1.
On average you need to mine 6570 pay-dirt (or 235 full inventories, rounded up) to obtain enough nuggets for the full set.
Cheap first[edit | edit source]
Purchasing the boots, helmet, legs, and jacket, in that order gives:
(30x * y) + (40x * y * 1.002) + (50x * y * 1.006) + (60x * y * 1.012) = 396,569 XP
Substitute 1 for x and y:
30 + (40 * 1.002) + (50 * 1.006) + (60 * 1.012) = 181.1
Expensive first[edit | edit source]
Purchasing the jacket, legs, helmet, and boots, in that order gives:
(60x * y) + (50x * y * 1.008) + (40x * y * 1.014) + (30x * y * 1.018) = 397,445 XP
Substitute 1 for x and y:
60 + (50 * 1.008) + (40 * 1.014) + (30 * 1.018) = 181.5
Conclusion[edit | edit source]
Based on the above numbers, over the time it takes to obtain the set, it is more efficient if players start with the most expensive items first, because the incremental xp boost over time will be higher than with the smaller xp boosts while obtaining the nuggets for the higher tier items.
