Full Prospector is needed for a Master Clue, Varrock armour 4 can be used.
|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 cheaper items first, even though they offer a lower boost per nugget. 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. Pay-dirt is received at a constant rate of 2.94%, 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.
Purchasing the boots, helmet, legs, and jacket, in that order gives:
(30x * yx) + (40x * yx * 1.002) + (50x * yx * 1.006) + (60x * yx * 1.014)Substitute 1 for x and y:
30 + (40 * 1.002) + (50 * 1.006) + (60 * 1.014) = 181.1
Purchasing the jacket, legs, helmet, and boots, in that order gives:
(60x * yx) + (50x * yx * 1.008) + (40x * yx * 1.014) + (30x * yx * 1.018)Substitute 1 for x and y:
60 + (50 * 1.013) + (40 * 1.025) + (30 * 1.035) = 181.5
Based on the above numbers, over the time it takes you to obtain the set, you're better off starting with the cheaper items first because the incremental xp boost over time will be higher if you have smaller xp boosts while obtaining the nuggets for the higher tier items.
- Similar to the Desert robes and various other desert-related items, wearing the full Prospector Kit in the desert will reduce the amount of waterskins needed to survive. This was confirmed by Mod Ash during the RuneScape Mythbusters Special - Ep. 2 on Jagex's official Old School RuneScape YouTube channel.
