# Recharge

## Definition

**Recharge** refers to the time, in seconds, between two uses of a given power. This length of time may be shortened in several ways:

- slot one or more Recharge Rate Enhancements in a power;
- use another power (such as Hasten) or an Accolade Power (such as Geas of the Kind Ones);
- receive a buff (such as Speed Boost or Accelerate Metabolism);
- utilize Invention Origin Enhancement Sets that grant recharge bonuses;

or any combination of these.

Reductions to recharge rate do not apply intuitively. A recharge rate buff of +100% or more does not make the power recharge instantly. Instead, use this formula:

`RechargeTime = BaseRechargeTime / ( 100% + Buffs - Debuffs )`

where Buffs includes all bonuses mentioned above. A 100% enhancement thus cuts the recharge time in half. A 200% enhancement cuts it by two thirds. Since the enhancement is in the denominator, it is subject to diminishing returns — the more you add, the less each new amount helps.

Recharge rates are subject to minimum and maximum limits.

## Categories

The long text descriptions of powers rate their *base* recharge time in one of six broad categories. The following table is a rough approximation of the time, in seconds, covered by these categories.

Very Fast | Less than 3 seconds |
---|---|

Fast | 3 to 4 seconds |

Moderate | 4 to 10 seconds |

Slow | 10 to 60 seconds |

Long | 60 to 240 seconds |

Very Long | More than 240 seconds |

## Recharge Shuffle

Because a recharge buff may end before a power is finished recharging, calculating how long a power takes to recharge can be confusing. For example, Hasten has a 450s recharge, but it grants a 120s recharge buff.

One way to visualize this, as given by DrMike2000 on the official forums:

- The best way to think about it is that Hasten (and all powers) recover 1 point per second. Hasten needs 450 points to recharge.

- Recharge buffs change the number of points you accumulate every second, so with hasten active, you get 1.7 points back per second for each power that's recharging.

- So, click Hasten. For the next 120 seconds you accumulate 120*1.7 = 204 points
- You still need another 246 points for Hasten to recharge, and will have to wait 246 seconds for them to accumulate at 1 point per second.

- So the total recharge time will be 120 + 246 = [366] seconds.
