Strategy

 * Getting Catalyst the Protector allows you to be much more aggressive during early laning, however when you get to higher levels and you level up much slower, the effect is severely diminished.
 * It is a very strong laning item choice for most champions. If you are planning on getting a or, you should consider taking a Catalyst as your first item. This is because it helps with early and mid-game laning, especially on a squishy character.

Trivia

 * The symbol on the side of the stone is likely the symbol for infinity. It is used on certain champions who have abilities that regenerate mana/health allowing them to stay in battle much longer than their opponents, allowing them to push effectively.
