Personal Shields
These are different from the Shields carried by Templars in that every character has these shields and unless the attacker has shield penetration all the damage is taken by these shields and the character suffers no loss of health or any risk of an Elemental Effect until they run out. From this point onwards all damage that is not absorbed by the characters armor is taken off the characters health and the character is at risk of an Elemental Effect as well as receiving damage.
The amount of shields a character currently has is shown as both a yellow bar around the health orb in the left hand corner and as a number below the health orb. As the amount of shields drop the yellow bar turns red and starts flashing as a visual warning.
These shields are regenerated when not under attack by a varying amount per minute depending on the character class and equipment used.
Shield Boosters are used to replenish and temporarily increase the amount of shields a character currently has.
