Mods used to create this mod

The root projekt is TinkersSatchel:

For the UI i took parts of Crashaholics UIModifier mod:

And the Multiplayer UI support is based on the Example of MiniRPC:

What does this mod do

With the artifact active, players have a chance to gain items after defeating monsters, but lose items upon taking damage.

There are three new UI-Elements added. There are two sidebars which show the last ten gained/lost items and a progress bar which fills till you get an item.
In the Sidebars are only the items shown which you obtained/lost by the mod. The UI resets every stage.
In the following image you can see these elements:

If you don't like some or all of the added components you can disable them in the settings. Additionally you can turn on a chat output in exchange.

When do i get an item

There are two possible gamemodes.

Default mode

The calculation for the required kills is:
(totalItems - currentStage * averageItemsPerStage) ^ exponentTriggerItems
totalItems is the current item count of each character. CurrentStage is the number of stages completed and exponentTriggerItems and averageItemsPerStage can be changed in the config file.
For example you've 20 items and are on stage 5. The configured averageItems are 3 (default). That means you've to kill (20-5*3)^2=25 enemies to get one item.

Everytime you get hit you'll lose an item. The only exception is if you've less items then the configured minItemsPerStage.
If that is the case you have a chance that you will not use an item.
The calculation for this is:
minItemsPerStage can be configured in the setting. For example you've 6 items and are on stage 5. The configured minItemsPerStage are 2 (default).
So you've the calculation:
(6/(2*5))^0.5=0,77 that means you've a change of 77% to not lose an item.

On the other hand the possibility increases if you've more items than you should have to lose more than one item. The formular to calculate that is:
(totalItems) / (maxItemsPerStage * currentStage)^exponentailFactorToCalculateSumOfLostItems
maxItemsPerStage and exponentailFactorToCalculateSumOfLostItems are configurable and have a default value of 7 and 1.5.
For example you've 50 items, are on stage 5 and have the default values so you calculate:
(50 / (7 * 5))^1.5=1.7
So you'll have a 100% chance to lose one item and 70% chance to lose another.

Sacrifice like mode

The Sacrifice like mode can be enabled in the settings. If it's enabled you've a chance to get an item with every enemy. The base chance for getting an item is 10%.

Other mechanics

After you lost an item you'll get a short buff that prevents you from loosing another one. The length of that buff depends on the difficulty and can also be configured with the config entitys "timeAfterHitToNotlose".
The default settings are 0,8 second protection on Drizzly, 0,2 on Rainstorm and 0.05 seconds on Monsoon

Character specific settings

In the settings you can specify for each character how many items he'll get if he kills enough enemys and if he has an additional multiplier to the buff after loosing an item. The default settings are that every meele char has a 4 times longer buff and Artificer get double as many items if he kills enough enemies.

Custom Characters

Custom character don't have character specific settings by default. But you can add them in the config file. To do so edit CustomCharacters and set the values in json format.
[{"Name": "AATROX_NAME", "MultiplierForTimedBuff": 2.0, "BonusItems": 1.0},{"Name": "MINER_NAME", "MultiplierForTimedBuff": 2.0, "BonusItems": 2.0}]
The name of the character is written in the console after killing an enemy or loseing an item. You can add as many characters as you need. Just add them seperated by ",".
You don't have to escape the " by doing \" but the default setting is escaped.
