Sacred Shield is an extremely efficient spell, that puts a shield on your target to prevent damage.

Sacred Shield is an instant cast spell. Like all instant cast spells, it is effected by haste to bring down the global cool down.

The spell's base costs is 527 mana.

The best way to explain how Sacred Shield works is: First of all, it puts on the main buff called "Sacred Shield". When your target takes damage, it triggers placing another buff, which is also called "Sacred Shield". This second buff lasts up to 30 seconds, absorbing 500 damage (600 when talented) plus an amount based on your spell power.

The second Sacred Shield buff cannot trigger more than once every 6 seconds.

The first buff lasts 30 seconds normally, and when talented (you get it with the holy/prot spec), it will last 1 minute doubling its efficiency.

The second Sacred Shield buff also will give you a extra 50% chance to crit for Flash of Light spells. Believe it or not, this ability isn't really worth paying much attention to. If it happens, it happens. If it doesn't, it doesn't.

While the first Sacred Shield buff is active, your Flash of Light spells will place a heal over time on the target. See "Flash of Light" on this site for more information.

Before you get any ideas of casting it so this buff is on everyone in your raid/group, don't. It can only be up on one person at a time. If you cast it on another, the previous one falls off.

The best thing about Sacred Shield is that it can help avoid a wipe when placed the tank(s). It often smoothes out the spike damage making it easier to heal the tank.

Healing Amounts:

There are 3 buff's that adjust the way that you calculate your heal strength based on your Spell Power. That is the Healing Light talent, the Divinity talent and Improved Devotion Aura / Tree of Life Aura (These don't stack).
