Nano Forge
The Nano Forge is a device found in most station that allows players to upgrade the base damage of weapons and base armor and shields of armor. Upgraded items are denoted by a +X affix applied to the item name, where X is the number of upgrades. For example, a Hu's Hypershot that has 3 successful upgrades becomes a +3 Hu's Hypershot.
Success & Failure
The first 2 upgrades (or nanos) are guaranteed to succeed. Any item with 2 or more nano upgrades has the potential to fail further upgrades at a declining rate of success. Further more, the cost of each upgrade increases each time a nano succeeds. Should a nano fail, the current number of upgrades on the item are roll-back a random number of intervals. This is true until the number of upgrades on a item reaches level 6 where a failed nano will result in the item being destroyed, returning a random quantity of nanoshards. The higher upgrade, the more nanoshards that are returned.
When a player nanos a +7 item or higher - a system message is broadcasted across the server, revealing their name and whether or not the upgrade was successful.
Using the Nano Forge
The player drops the item they want nano forge into the top most grid, where the text says place item here. The nano forge then informs the player what resources and how much palladium is required to perform the upgrade.
A device or enchanter may be placed in the single grid place to increase the nanos chance of success.
A detailed analysis on the chances and required resources can be found here: Mathematical Analysis of the Nano Forge
