Masteries are one of the two level-dependent aspects of the persistent summoner system.  They do not require IP or RP.

There are three mastery trees: Offense, Defense, and Utility. Mastery points are spent on upgrading your champion's abilities ingame.

You are restricted in which upgrades you can purchase by a hierarchical ordering.  You must first purchase the upper upgrades in a tree before you can purchase lower (and usually more powerful) upgrades.  Some upgrades are specifically linked to an upgrade directly above them - you must 'max out' that upgrade before you can purchase any of the lower one.

The reward for reaching the bottom of a tree is a single very significant upgrade.  Because of the amount you must invest in that tree, you can only 'max' out a single tree for any particular game.

You can freely reallocate masteries between each game.
