Auras

Auras are a type of Persistent Effect that radiate from a source—typically a creature, object, or magical construct—and move with it. While most auras are mobile, some may be anchored to a fixed location. An aura represents a continuous area of supernatural or extraordinary energy that influences its surroundings for as long as the effect remains active.

An aura has a defined radius that determines the area it affects. It may grant ongoing benefits, impose hazards, or trigger specific effects. Auras are commonly created by powers, creature abilities, or magical items. Like most Persistent Effects, overlapping auras—even of the same type—stack with each other unless otherwise specified.

Damaging Auras

Damaging auras are among the most common types. They are often represented in shorthand format, with damage expressed as a flat value or as dice:

For example: `Aura (10ft) Cold (10)` deals 10 points of Cold Damage each round to creatures within 10 feet of the source.

Activation

Some auras are passive and always active, especially those that are innate to a creature. Others require activation through a power or similar ability. Creatures with natural auras may or may not have the ability to suppress them, depending on the specific effect.
