You create a quasi-real barrier in the shape of a sphere that shimmers with golden sparkles and moves with you. Creatures and objects can enter or leave the area unimpeded. A breath barrier blocks fog, foglike effects, and gases created by spells such as fog cloud or cloudkill or by breath weapons that are poison gas.
When used as a barrier against breath weapons that deal hit point damage direction, the sphere absorbs up to 60 points of damage from one or more breath weapons before collapsing (at which time the power ends). A breath barrier takes damage as though it were a creature that failed its saving throw against the breath weaopn being used.
For every 2 additional power points you spend, the barrier can absorb an additional 12 points of breath weapon damage before collapsing.
