Salvaging for Ectoplasm: An Analysis

4248

Abstract (TL;DR)

An analysis of the salvage rates of Globs of Ectoplasm was carried out comparing the rates of acquisition between Black Lion Salvage Kits and Master's Salvage Kits. 50 Carrion Masquerade Masks were salvaged using 25 of each kit. Results point toward the two kits being functionally equal when salvaging for ectoplasm as well as incidental materials but in order to confirm this a larger study is needed.

Background

There has been a great deal of misinformation about salvaging for Globs of Ectoplasm floating around. What is known for sure is that they are salvaged off of level 70 or higher rares and exotics (please note that page is slightly out of date at the time of this writing I will update the information soon). However, people tend to disagree on which salvage kit between the Black Lion (bought with gems) or Master's (vendor item) has better Ectoplasm results. Following one such heated disagreement this morning I decided to set out, using what funds I can spare, to end this once and for all.

Hypothesis

Due to Master's Salvage Kit's 25% chance to recover rare materials they will yield a higher rate of Ectoplasm. The expected value should be 2.5 times more of Glob[s] of Ectoplasm with the Master's Salvage Kit than the Black Lion salvage kit. (To avoid confusion: LATER DISPROVED)

Methods and Materials

Using Tailoring 50 Carrion Masquerade Masks were created. Base Materials:

200 Bolts of Silk 50 Cured Thick Leather Squares 750 Large Bones 550 Spools of Silk Thread

The Black Lion Salvage Kit that was used was acquired in a Black Lion Chest.

The Master's Salvage Kit was acquired from Cinea in Divinity's Reach.

The Crafting and Salvaging was done in gear that has 0 Magic Find in order to eliminate possible erroneous results in the extreme unlikelihood that it has an effect on salvaging.

All Crafting and Salvaging was done within Divinity's Reach and at the exact same location for all repetitions of the respective processes. I did all the making without moving in between the 1st and 50th and the same with all the salvaging. I did relocate a few feet away between the end of crafting and the beginning of salvaging to avoid incidental bystanders from appearing in screen shots.

In order to avoid possible interactions with the, frankly stupid, anti-bot script I alternated between the salvage kits so that if an interaction were to occur it would occur to both at roughly the same rate.

Results

A link to the spreadsheet can be found here. From the salvaging of 50 Carrion Masquerade Masks 47 Globs of Ectoplasm were recovered as well as 98 Silk Scraps. The Black Lion Salvage Kit yielded 23 (x=0.92) Globs of Ectoplasm and 53 (x =2.12) Silk Scraps. The Master's Salvage Kit yielded 24 (x =0.96) Globs of Ectoplasm and 45 (x =1.8) Silk Scraps.

While not shown in the linked table, using the aforementioned methods did not result in any diminishing returns that would be a consequence of the anti-bot code. Taking the derivative of the data shows what is essentially a horizontal line. Therefore, if there are limitations in place on the number of salvages the game allows you to make it is N>50. (one would expect a negative slope in the case of limitations)

(x should be x-bar, a symbol for mean/average, but reddit didn't like it)

Discussion

The results in this pool of data show that each of the salvage kits have roughly the same chance of yielding an ectoplasm. The anomalies seen in the silk count are within the [god awful] standard deviation and with a larger sample group are expected to be roughly the same. No matter which of the two kits you decide to use it seems like you can count on about one ectoplasm. To confirm this a much greater study needs to be done (N=500+). Because the values of these two are so similar it may be worth while to test small sample groups of the lesser masterwork, fine, and common salvaging kits to see if all kits have the same salvage rate of ~1.

While this is by no means conclusive, it does provide us with useful information. Because of this I can firmly recommend Master's Salvage Kits for everything except if you need to recover an upgrade component. This is because of the 25% chance to recover rarer materials. While this clearly does not cover Globs of Ectoplasm or have any effect on crafted items (I put in silk and got only silk back) if salvaging a world drop it may yield tier 6 metal, cloth, leather, or wood components. Pending the results of further testing salvaging crafted items with lesser kits may also prove to be a substantial money saver.

Personal Notes

First, allow me to apologize for the spreadsheet. I am well aware that it was not done in the most efficient way possible but it has been a while since I have had to use one in an efficient manner therefore I went with how I was comfortable. My second apology is to anyone with a grasp on statistics, I know, I am sorry, the data set bothers me too but it is the best I could do with what I had. Furthermore, if you have any questions, comments, suggestions, or flames(<3) you can contact me in game or on this thread (Or if anyone is interested in conducting further research).
