Breath Weapon (Su)

Source: Advanced Player's Guide, p. 63

An eidolon learns to exhale a cone or line of magical energy, gaining a breath weapon. Select either acid, cold, electricity, or fire. The eidolon can breathe a 30-foot cone (or 60-foot line) that deals 1d6 points of damage of the selected type per HD it possesses. Those caught in the breath weapon can attempt a Reflex save for half damage. The DC is equal to 10 + 1/2 the eidolon’s HD + the eidolon’s Constitution modifier. The eidolon can use this ability once per day. The eidolon can use this ability 1 additional time per day by spending an additional 1 evolution point (maximum 3/day). The summoner must be at least 9th level before selecting this evolution.
