i was calculating the benefits of enchanting tools
http://www.minecraftwiki.net/wiki/Enchantingim going to share some calculations here
feel free to correct any of them
besides silk touch there are 3 enchantments
Unbreaking, Fortune and Efficienty
--------------------------------------------------------------------------------------------
Unbreaking calculation
--------------------------------------------------------------------------------------------
"The tool will last an entire tool durability longer."
in other words
unbreaking I means
your pickaxe will last, for the same time as 2 pickaxes would
unbreaking II
1 pickaxe = 3 pickaxes
III = 4 pickaxes IV 5 pickaxes and V 6 pickaxes
so if unbreaking III gives you 4 pickaxes this should also mean, the cost to buy would be 1 pickaxe x4
-------------------------------------------------------------------------------------------------
Fortune calculation
-------------------------------------------------------------------------------------------------
following to wiki, you will get extra ores when mining
I: (33% more)
II: (75% more)
III: (120% more)
so when you buy Fortune II, the cost to buy would be 1.75x the normal price(when only using it on ores tho!)
-------------------------------------------------------------------------------------------------
Efficienty calculation
-------------------------------------------------------------------------------------------------
"+50% mining speed per level. "
so Efficenty II means you dig 100%(normal) + 50%(I) + 50%(II) = 200% or, twise as fast
does this also means it should cost twise as much? no
say you dig for 10 minets and earn 100$ every minet
with a regular pickaxe you would earn 1000$
with an efficienty II you will stil earn 1000$ but in 5 minets
in those other 5 minets you can earn another 5x 100$ = 500$ with a normal pickaxe
you wont earn 2000$, you will earn 1500$, so 1.5x the price
-------------------------------------------------------------------------------------------------
All calculations
-------------------------------------------------------------------------------------------------
Adding everything up, the costs of enchantment should be as following
Unbreaking I II III IV V
price 2x 3x 4x 5x 6x
Fortune I II III
price 1.33x 1.75x 2.2x (ores only tho)
Efficienty I II III IV V
price 1.33x 1.5x 1.6x 1.66x 1.72x
-------------------------------------------------------------------------------------------------
Testing
-------------------------------------------------------------------------------------------------
now that i got it all calculated, lets go compare it with the prices people sell it for?
for example Unbreaking III, Fortune III, and Efficiency V
lets calculate? howmuch does a diamond pickaxe costs? 3 diamonds and 2 sticks
howmuch does a diamond cost? 100-150 + 2 sticks,
so a diamond pickaxe costs 450 at most?
now lets apply the benefits,
Normal pickaxe : 450
Fortune III (price x 2.2) 450 x 2.2 = 990
Efficiency V (price x 1.72) 990 x 1.72 = 1702
Unbreaking III (price x 4) 1702 x 4 = 6811
calculating the same with a pickaxe costing 300, results in 4540
so a fair price for this pickaxe would be 4540-6811
now lets compare it to the up to date price people buy it for
http://www.opticraft.net/index.php/topic,11122.0.htmlthats 10 times the price i calculated!!!???omg???!!!
how is this possible? why are they buying it for this much?
they require lots of effort to get, and effort = time = money...ok
but hey, what does a buyer care about howmuch the seller has put effort in it?
if it does not benefit that much, and costs such an ammount, why on earth are people buying it?
like unbreaking IV sounds epic and expensive, but hey 5 pickaxes are just the same...only a bit of inventory space...
feel free to share your idee's or correct any calculation
