Orokin Reactor

"Reactor used to super-charge Warframes."

- In-Game Description

The Orokin Reactor is an item used to supercharge Warframes, Sentinels, and Kubrows, doubling their mod capacity.

Acquisition
Orokin Reactors can either be bought for 20 or assembled in the Foundry after finding its blueprint. These blueprints can be obtained in one of three ways: After being built the blueprint disappears. To build another Orokin Reactor the player must obtain another blueprint.
 * 1) From alert missions. (An alert mission every other friday will give a Reactor or Catalyst )
 * 2) From login reward lottery system
 * 3) From Invasion missions

Applying Orokin Reactor to Warframes or Companions
To apply an Orokin Reactor after obtaining it, click Equip and select the desired warframe or companion you wish to upgrade. Select Upgrade, and click the UPGRADE button above your loadout selection. (Requires update as of update 14.5)

How it works
An applied Orokin Reactor will double the mod capacity of a warframe or companion. This increases the total power that can be consumed by mods, but not the number of mod slots. A rank 1 warframe with a Reactor installed will have a capacity of 2, which will increase to 60 at rank 30. Unlike Formas, Reactors can only be applied to a warframe or sentinel once.

'An Orokin reactor can be installed at any time. The capacity of the warframe or sentinel it is applied to will always be double that of its rank.'
