rift item:Planar Focus  

A Planar Focus is an item that is equipped on the player like a piece of armor or weapon.

There are different types of Planar Focus', with each one opening more or less slots to put in Planar Essence items.

The first few that a player will get has 2 Lesser Slots, and is available from the Planar Focus dealer in each factions starting zone. That dealer will also sell a Planar Focus with 3 Lesser slots for a price. As the player goes further into the game, and reaches higher level areas, the Planar Focus dealer in that zone will have bigger and more available Focus' for purchase.

See Planar Essence for descriptions of what they do.
