RNG Tests

Method & Disclaimer
 are performed by gathering an adequate amount of the item (mostly lockboxes of various kind) one want to test on the live server on any character and then bring repeated, sequential copies of that character to the preview shard. The item can then be gathered by the ingame mail system in case it is BoE or BtA (bind to account). Alternatively one has to do the tests separately on every copied character and accumulate the results. The higher the original amount on the live server the less copies are needed to achieve a good sample size.

The higher the sample the closer one get to the actual drop rates of the item. One should note that numbers acquired through these tests are never absolute. The tests assume that the game uses a random number generator, but the real system that generates the probabilities is unknown. Also, the approximated drop rates are only true for the build they've been tested on and may not reflect the actual drop rates on the current live build, because anything on the preview shard is subject to change before the most recent build is sent to the patch server.

This information was recently removed from the official Neverwinter forums because it is unofficial and drop rates will never be published. Treat the provided information with due care.

Values
This should serve as a quick overview of the value in of those items in the Lockboxes that can be priced using the Auction House. This excludes the BoP fashion and currency items. Rough Astral Diamonds are treated as Astral Diamonds for the calculation. These values are generated with the information of the RNG tests and have to be treated with the same caution. Please refer to the disclaimer above for more details.

General Observations

 * Elixir of Life and Ardent Potions drop with regular Potions 10% of the time

 * 3x
 * 2-3x
 * 1x other
 * ,, , doesn't drop

Refiner's Cache
Date: Jan 26th 2014

Build: NW.14.20140123a.1 (preview shard)

Sample: 1,800

On the preview shard the boxes were bugged during the test and were not dropping the normal Enchantments. Starting with the live Patch NW.10.20140113a.7 the boxes also drop s, s, and in the upper tier for the. Limited testing on the live shard indicates a 3:2:1 ratio between Lesser Marks, Peridots and Aquamarines.

Waukeen's Coin Purse
Date: Jan 10th 2014

Build: NW.10.20131211a.12 (preview shard)

Sample: 2,880

Waukeen's Strongbox
Date: Jan 10th 2014

Build: NW.10.20131211a.12 (preview shard)

Sample: 1,640

The drop rate of the Coins is too low because of a bug. Once the currency tab in the inventory was full and couldn't hold any more coins, these just stopped dropping and were replaced by another item from the list. The last Coins dropped in Box #1,222 and that the RNG generates over 400 Strongboxes without Coins is basically impossible.

Gift of Tymora
This initial version of the Gift dropped from the first installment of the Tymora's Gift event. Date: Jan 10th 2014

Build: NW.10.20131211a.12 (preview shard)

Sample: 2,049

Gift of Tymora II
This version of the Gift dropped from the second installment of the Tymora's Gift event. Date: Mar 7th 2014

Build: NW.14.20140224a.7 (preview shard)

Sample: 6,000

Gift of the Gods
Date: Feb 7th 2014 & Feb 17th 2014

Build: NW.10.20140128a.4 & NW.10.20140211a.5 (owlbear shard)

Sample: 3,000 + 4,000

This has been tested after the had already dropped. Limited testing with 25 characters returned a drop chance of 6.78% for the Gift itself.

General Observations
Although not incorrect, the tooltip of Profession Chests is quite misleading:
 * The only uncommon profession items that drop from Chests are s and
 * Uncommon profession items that can be bought from M'tari Prin'tal are treated as a common drop
 * Common profession items that can be bought from M'tari Prin'tal drop in sets of three, but are treated as only one common resource.

A Barrel of Goods
Date: Feb 3rd 2014

Build: NW.10.20140128a.0 (owlbear shard)

Sample: 3,000 (Because the Barrel drops three items from the list, the real sample is 9,000)

The drop rates can probably be divided into four tiers:
 * The first tier consists of the potions and skill kits that drop at 25% each
 * The second tier consists of the profession resources, runestones and enchantments and drop at around 10-12% each
 * The third tier consists of the refining gear and drops at around 3% each
 * The fourth tier is the upgraded Large Chest at 1% (though actually 3% of the Barrels get upgraded)

When the Barrel gets upgraded to the Chest, one of the three rewards is converted into the upper loot, but the other two drop as well. It is unknown whether this is intended or a bug.
