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

What does this mod do

This mod gives you items after killing some enemies. But you'll loose items if you get hit.

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 loose 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 23% to not loose an item.

On the other hand the possibility increases if you've more items than you should have to loose 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 loose one item and 70% chance to loose another.

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 "timeAfterHitToNotLoose".

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.

I'm not sure if the buff and the character specific settings make the game too easy. So if you think so just change the settings or tell me what the perfect settings are.


On the left side there are the symbols of the gained items. These are only the items which you obtained by the mod. On the right side there are all lost items. The UI resets every stage.
