Focus 1.0

The Mod previously known as Focus is now Intensify

Focus is an end-game element that was released in Update 18.

When a piece of gear hits its rank cap, it can start earning points to unlock player abilities they can activate as a form of Transcendence state.

Focus is classified into five Tenno "Schools":
 * Warrior (Madurai Lens) - Ability is laser.
 * Guardian (Vazarin Lens) - Ability is healing waves. Lens focuses on heals, revives and shields.
 * Tactician (Naramon Lens) - A melee based Lens, ability is a wave of stuns.
 * Elemental (Unairu Lens) - Ability is petrify
 * Channeling (Zenurik Lens) - Ability is Stomps

You need to install a "Focus Lens" on your maxed Warframe or Weapon to start earning Focus points, the types of Focus points earned depends on which lens are used. For example, installing a Warrior Lens on a Warframe will earn it Warrior Focuses. All affinities earned beyond a rank 30 Focused item goes toward earning a Focus point. (Example Focus on a rifle, the rifle must get the kills, using melee while having Lens-equipped rifle on your back does not gain Focus for the lens...) Also, KILLS and assists (not specifically Affinity) seem to give specific focus points (needs testing)

Every mastery ranks earned will grant a Focus slot. e.g.: Being Mastery Rank 4 will allow you to install four Focus powers.

It is stated that Focus will outline lore based on the Tenno's background.

The default keybinding to use your Focus ability is "5".

Pool (Starts at 4/5) can be increased by paying Focus points, this pool indicates the number of abilities/side abilities you can have in the tree.
