Power Block

A power block or "PB" refers both to a source power and the associated affliction status which disables the use of any powers, weapon styles, or stances for a short time. Much like a stun, once a power block has been used on a person, he receives a temporary power block immunity to prevent a chain.

Archmage

The Archmage power "Chant of Mastery" will provide an Elf mage with between two and three minutes of immunity to power blocks.
