Metabreath Feats

These are all the metabreath feats that have been found, so far.

Clinging Breath

Source
Draconomicon
Your breath weapon clings to creatures and continues to affect them in the round after you breathe.
Prerequisite
Con 13, breath weapon.
Benefit
Your breath weapon has its normal effect, but also clings to anything caught in its area. A clinging breath weapon lasts for 1 round. In the round after you breathe, the clinging breath weapon deals half of the damage it dealt in the previous round. Creatures that avoid damage from the breath weapon (such as creatures with the evasion special quality or incorporeal creatures) do not take the extra damage. For example, an old silver dragon uses its cold breath and deals 72 points of cold damage (or 36 points against a target that makes its save). In the following round, foes that failed their saves against the breath weapon initially take an additional 36 points of cold damage, and foes that succeeded on their saves take 18 points of cold damage.

A foe can take a full-round action to attempt to remove the clinging breath weapon before taking any additional damage. It takes a successful Reflex saving throw (same DC as your normal breath weapon) to remove the effect. Rolling around on the ground grants a +2 bonus on the saving throw, but leaves the foe prone. A clinging breath weapon cannot be removed or smothered by jumping into water. A clinging breath weapon can be magically dispelled (DC equal to your breath weapon save DC).

This feat only works on a breath weapon that has instantaneous duration and that deals some kind of damage, such as energy damage (acid, cold, electricity, fire, or sonic), ability damage, or negative levels.

When you use this feat, add +1 to the number of rounds you must wait before using your breath weapon again.
Special
You can apply this feat more than once to the same breath weapon. Each time you do, the clinging breath weapon lasts an additional round.

Empower Breath

Source
Original
Your breath weapon is particularly powerful.
Increase the number of dice rolled by 50%.

When you use this feat, add +2 to the number of rounds you must wait before using your breath weapon again.

Enlarge Breath

Source
Draconomicon
Your breath weapon is larger than normal.
Prerequisite
Con 13, breath weapon.
Benefit
The length of your breath weapon increases by 50% (round down to the nearest multiple of 5). For example, an old silver dragon breathing an enlarged cone of cold produces a 75-foot cone instead of a 50-foot cone. Cone-shaped breath weapons get wider when they get longer, but line-shaped breath weapons do not.

When you use this feat, add +1 to the number of rounds you must wait before using your breath weapon again.

Extend Spreading Breath

Source
Draconomicon
You can convert your breath weapon into a spread effect that can be used at range.
Prerequisite
Con 15, breath weapon, Shape Breath, Spreading Breath, size Small or larger.
Benefit
You can modify your breath weapon so that it fills a spread centered anywhere within a short distance of your head. The range and size of the spread depends on your size, as shown below.

Dragon Size Spread Radius Spread Range
Small 10 ft. 40 ft.
Medium 15 ft. 60 ft.
Large 20 ft. 80 ft.
Huge 25 ft. 100 ft.
Gargantuan 30 ft. 120 ft.
Colossal 35 ft. 140 ft.

When you use this feat, add +2 to the number of rounds you must wait before using your breath weapon again.

Heighten Breath

Source
Draconomicon
Your breath weapon is even more deadly than normal.
Prerequisite
Con 13, breath weapon.
Benefit
You can increase the save DC of your breath weapon by any number up to a maximum equal to your Constitution bonus.

For each point by which you increase the save DC, add +1 to the number of rounds you must wait before using your breath weapon again.

Lingering Breath

Source
Draconomicon
Your breath weapon forms a lingering cloud.
Prerequisite
Con 15, breath weapon, Clinging Breath.
Benefit
Your breath weapon has its normal effects, but also remains as a lingering cloud of the same shape and size as the original breath weapon. This cloud lasts 1 round.

Foes caught in the breath weapon’s area when you breathe take no additional damage from the lingering breath weapon, provided they leave the cloud by the shortest available route on their next turn. Otherwise, anyone who touches or enters the cloud while it lasts takes one-half of the breath weapon’s normal effects; any saving throw the breath weapon normally allows still applies. Damaging breath weapons deal one-half their normal damage, and breath weapons with effects that have durations last for half the normal time. If a creature is affected by the same non-damaging breath weapon twice, the effects do not stack.

For example, an old silver dragon uses this feat on its cold breath weapon. Creatures caught in the 50-foot cone take 16d8 points of cold damage, and a DC 31 Reflex save reduces the damage by half. The 50-foot cone lingers for 1 round. While the cone lasts, anyone touching or entering it takes 8d8 points of cold damage, and a DC 31 Reflex save reduces the cold damage to 4d8 points. Creatures in the cone when the dragon breathed take no additional damage if they leave by the shortest available route on their next turn.

If the same dragon uses this feat on its paralyzing breath weapon, a creature caught in the 50-foot cone must make a DC 31 Fortitude save or be paralyzed for 1d6+8 rounds. The 50-foot cone lingers for 1 round. While the cone lasts, anyone touching or entering it must make a DC 31 Fortitude save or be paralyzed for 1d3+4 rounds. Creatures in the cone when the dragon breathed take no additional damage if they leave by the shortest available route on their next turn. Creatures paralyzed by the initial breath cannot leave the cloud, but suffer no additional effects because the paralyzing effects do not stack.

When you use this feat, add +2 to the number of rounds you must wait before using your breath weapon again.
Special
You can apply this feat more than once to the same breath weapon. Each time you do, the lingering breath lasts an additional round.

You can apply this feat to a breath weapon that also has received the Clinging Breath feat, but the resulting breath clings only to foes caught in the initial breath.

Maximize Breath

Source
Draconomicon
You can take a full-round action to use your breath weapon to maximum effect.
Prerequisite
Con 17, breath weapon.
Benefit
If you use your breath weapon as a full-round action, all variable, numeric effects of the attack are maximized. A maximized breath weapon deals maximum damage, lasts for the maximum time, or the like. For example, an old silver dragon using a maximized cold breath weapon (damage 16d8) deals 128 points of damage. An old silver dragon using a maximized paralysis gas breath weapon (duration 1d6+8 rounds) paralyzes creatures for 14 rounds if they fail their saving throws.

The DCs for saving throws against your breath weapon are not affected.

When you use this feat, add +3 to the number of rounds you must wait before using your breath weapon again.

This feat stacks with the effects of breath weapons enhanced with other metabreath feats, but does not maximize them. For example, a maximized breath weapon further enhanced by the Tempest Breath feat produces the type of wind effect noted in that feat description, but the velocity of the wind is not also maximized.

Special
You cannot use this feat and the Quicken Breath feat on the same breath weapon at the same time.

Quicken Breath

Source
Draconomicon
You can loose your breath weapon with but a thought.
Prerequisite
Con 19, breath weapon.
Benefit
Using your breath weapon is a free action. When you use this feat, add +4 to the number of rounds you must wait before using your breath weapon again.
Normal
You cannot use this feat and the Maximize Breath feat on the same weapon at the same time.

Recover Breath

Source
Draconomicon
You wait less time before being able to use your breath weapon again.
Prerequisite
Con 17, breath weapon.
Benefit
You reduce the interval between uses of your breath weapon. You wait 1 round less than usual before breathing again, but always at least 1 round. The feat stacks with the effects of metabreath feats, reducing the total time you must wait to use your breath weapon again by 1 round.
Special
If you have multiple heads with breath weapons, all breath weapons use the reduced interval.

Shape Breath

Source
Draconomicon
You can make the area of your breath weapon a cone or a line, as you see fit.
Prerequisite
Con 13, breath weapon, size Small or larger.
Benefit
If you have a line-shaped breath weapon, you can opt to shape it into a cone. Likewise, if you have a cone-shaped breath weapon, you can shape it into a line.

When you use this feat, add +1 to the number of rounds you must wait before using your breath weapon again.
Normal
Without this feat, the shape of your breath weapon is fixed.

Split Breath

Source
Draconomicon
You can split your breath weapon into a pair of weaker effects.
Prerequisite
Con 13, breath weapon, Shape Breath, size Small or larger.
Benefit
Your breath weapon retains its size and shape, but splits into two areas that you aim separately. Each portion deals half the damage the breath weapon normally deals or lasts half as long as the effect normally lasts.

For example, an old silver dragon that uses this feat on its cold breath weapon produces two 50-foot cones of cold that deal 8d8 points of cold damage each. If the same dragon used this feat on its paralyzing gas breath weapon, it would produce two cones of gas, each of which could paralyze a creature for 1d3+4 rounds.

You can aim the split breath effects so that their areas overlap. Creatures caught in the area of overlap are struck by both weapons and are affected twice, subject to all the normal rules for stacking magical effects.

When you use this feat, add +1 to the number of to you must wait before using your breath weapon again.

Spreading Breath

Source
Draconomicon
You can convert your breath weapon into a spread effect.
Prerequisite
Con 15, breath weapon, Shape Breath, size Small or larger.
Benefit
You can modify your breath weapon so that it fills a spread centered on your head instead of taking its normal shape. The radius of the spread depends on your size, as shown below.

Dragon Size Spread Radius
Small 10 ft.
Medium 15 ft.
Large 20 ft.
Huge 25 ft.
Gargantuan 30 ft.
Colossal 35 ft.
When you use this feat, add +2 to the number of rounds you must wait before using your breath weapon again.

Tempest Breath

Source
Draconomicon
You can make your breath weapon strike with the force of windstorm.
Prerequisite
Str 13, breath weapon, Power Attack, size Large or larger.
Benefit
When you use your breath weapon, in addition to its normal effects, creatures in the area are affected as through struck by wind effects. The force of the wind depends on your size, as indicated below.

Dragon Size Wind Force
Large Severe
Huge Windstorm
Gargantuan Hurricane
Colossal Tornado
Because your breath weapon has an instantaneous duration creatures ignore the checked effect unless they are airborne (in which case they are blown back 1d6x5 feet).

When you use this feat, add +1 to the number of rounds you must wait before using your breath weapon again.
