# Drains

destroy Resources

{% hint style="danger" %}
A Resource that goes into a Drain is permanently removed from a game's economy.
{% endhint %}

A Drain has the 4 [Activation Modes](/docs/nodes-properties/activation-modes.md) and the [Pulling & Pushing](/docs/nodes-properties/pulling-and-pushing-resources.md) actions of all other Nodes.

The rate of a Drain is determined by the flow rate of its input [Resource Connection](https://machinations.gitbook.io/docs/connections/resource-connections). Some Drains consume Resources at a steady rate, while others consume Resources at random rates or intervals.

:wrench: In the gif above, there are 3 examples of flow rates:

1. Shooter: The Shoot Drain consumes 1 Ammo every time the player shoots
2. Resource Management: The player has a cost of 1 coin every 2 weeks
3. Brawler: During a boss fight, player takes damage anywhere between 1 to 6 Health points (D6 notion), every time the boss hits.

:wrench: You can also set a Drain consume all Resource within a Pool by labelling the Resource Connection with `all`.
