喷吐武器（Su）：使用喷吐武器是一个标准动作。一旦龙使用了喷吐武器，它在1d4轮内不能再次使用。如果一条龙有超过一种的喷吐武器，它同样只能每1d4轮喷吐一次。一次喷吐攻击总是从与龙邻接的任意格子交叉点开始，并且沿着龙选择的方向延伸，范围注明在下面的表格中。如果喷吐武器造成伤害，在范围内的生物可以尝试通过反射豁免令伤害减半，DC根据龙的年龄层有所不同，在各种龙的表格中有标明。对抗无伤害的喷吐武器使用相同DC，使用何种豁免标明在各自的描述中。对抗喷吐武器的DC等于10+1/2龙的HD+龙的体质修正值。
原文：
Breath Weapon (Su): Using a breath weapon is a standard action. Once a dragon breathes, it can’t breathe again until 1d4 rounds later. If a dragon has more than one type of breath weapon, it still can breathe only once every 1d4 rounds. A blast from a breath weapon always starts at any intersection adjacent to the dragon and extends in a direction of the dragon’s choice, with an area as noted on the table below. If the breath weapon deals damage, creatures caught in the area can attempt Reflex saves to take half damage; the DC depends on the dragon’s age and variety, and is given in each individual entry. Saves against nondamaging breath weapons use the same DC; the kind of saving throw is noted in the variety descriptions. The save DC against a breath weapon is 10 + 1/2 dragon’s HD + dragon’s Con modifier.
附龙种原文（没讲动作）：Heart (Su): A dragonborn who chooses heart as her draconic aspect gains a breath weapon. The breath weapon is a bright, shining line that coruscates with every metallic color. The line’s length is 5 feet per Hit Die the dragonborn has, up to a maximum of 100 feet at 20 HD. The breath weapon deals 1d8 points of damage, plus an extra 1d8 points for each 3 HD the dragonborn possesses (2d8 at 3 HD, 3d8 at 6 HD, and so on). The damage can be acid, cold, electricity, or fi re, changing on each use as the dragonborn chooses. A uccessful
Refl ex save (DC 10 + 1/2 the dragonborn’s HD + her Con modifi er) halves the damage. A dragonborn can use her breath weapon once every 1d4 rounds.
