# Prospector kit

(Redirected from Prospector's outfit)
A player wearing the prospector kit.

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.

The full set, when worn, grants a 2.5% bonus Mining experience. In addition, wearing the full kit in the desert will reduce the need for waterskins, similar to the desert robes.[1]

Wearing full prospector while entering the Mining Guild is one of the tasks in the hard Falador Diary.

Full Prospector is needed for a master clue; Varrock armour 4 can be used.

## Obtaining

Item XP Boost Cost (in ) Sells for (in ) Boost per nugget
(% per )
Helmet +0.4% 40 32 0.010
Jacket +0.8% 60 48 0.013
Legs +0.6% 50 40 0.012
Boots +0.2% 30 24 0.007
Set bonus +0.5%
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. Nuggets are received from pay-dirt at a constant rate of 2.74%[2], 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.

#### Cheap first

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) = 462'664 XP

Substitute 1 for x and y:

30 + (40 * 1.002) + (50 * 1.006) + (60 * 1.012) = 181.1

#### Expensive first

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) = 463'686 XP

Substitute 1 for x and y:

60 + (50 * 1.013) + (40 * 1.025) + (30 * 1.035) = 182.7

#### Conclusion

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.
