Examine	Added to your toolbelt, provides power to all equipped Invention devices.

The Charge pack acts as a universal battery for augmented items. It is the first invention the player makes in the Invention Tutorial and is added to the toolbelt. It therefore cannot be dropped and is kept on death even if the player is skulled and dies with it.

On death, any augmented equipment which is not protected will drain two hours worth of drain rate when it is recovered; e.g. If a 1 charge/second drain weapon is not protected, it drains 7200 charges on recovery.

It is half-charged at 100,000 when players create it. More charge can be added by using a Divine charge.

Even if the Charge pack depletes, augmented equipment still retains its gizmos and experience and can still be equipped. However, augmented items no longer offer any bonuses without charges, and all gizmos lose their abilities. Augmented items do not level up without charges.

Higher invention levels allow players to research higher maximum charges.

Charge drain

Inspecting an augmenting item

Augmented items (whether or not they have gizmos) no longer use the equipment degradation system, and instead drain charge from the central charge pool each second of combat. This applies to all augmented items including those that did not degrade before augmentation. This rate depends on the item that has been augmented, and can be reduced by researching charge drain reduction.

The current drain rate for an augmented item is displayed in the Check right-click option. This shows both the drain rate of the item checked and the total drain rate of all worn augmented items.

Drain rate

The base drain rate of an item is dependent on its tier. Level 1 items drain at a rate of 0.97 charges per second.

For items level 70 and above, the drain rate per second $D$ follows:

$D={\frac {T-60}{7.2}}\times S\times E\times L$

Where:

• $T$ is the tier of the item
• $S$ is the slot modifier:

$S={\begin{cases}1.5&{\text{2-handed}}\\1.0&{\text{1-handed main-hand}}\\1.0&{\text{body- and leg- slot}}\\0.5&{\text{off-hand}}\end{cases}}$

• $E$ is the efficient modifier, for a rank $R$ efficient perk (if multiple gizmos contain efficient on a single item, only use the highest ranked)

$E={\begin{cases}1-(0.06\times R)&{\text{Efficient}}\\1&{\text{No efficient perk}}\end{cases}}$

• $L$ is the Equipment level modifier from the item's level $I$

$L={\begin{cases}1&I<5\\0.9&I\geq 5\end{cases}}$
