The Charge Meter
  • Charge Bar.gif

Charge is a mechanic implemented by Seeking Mechanisms and most of the weapons crafted with Dubious Plating and Mysterious Circuitry. Items that use this mechanic will display remaining charge in their tooltips. For these items, charge is required and also depleted when used, similarly to ammunition. Unlike ammunition, it does not directly require an extra inventory slot. The amount of damage on a weapon is dependent on its charge under the equation: Total Damage = Base Damage * 1.087 - 0.08 / (Current Charge / Max Charge + 0.07)

While the amount of charge is displayed on the tooltip as a percentage, charge is actually a number that varies from 0 to 250, depending on the tier and usage of the item. The amount of charge depleted per use is a constant that varies between each item. The amount of charge lost is calculated after item use, meaning the damage penalty will only apply for the next attack.

Charge can be added to weapons via the Charging Station, by inputting the item into the top slot, and a Draedon Power Cell at the bottom slot. Each Draedon Power Cell increases the amount of charge by 1 unit and is created every 15 seconds at a player-placed Power Cell Factory.

The amount of charge depleted in one single use and the maximum charge for each item is as follows:

  • The Gatling Laser, Hydraulic Volt Crasher, and Phaseslayer use 0.0075, 0.002, and 0.005 charge per frame respectively. The values above are equal to the amount of charge used multiplied with the amount of use time of these weapons.
