Low - Moderate - Bioweapon [Xenotheric]
Prerequisites: Con 13 or Int if the desired bioweapon is psionic (+4 for every subsequent instance of this feat)Benefit: You gain a special biological weapon. See below.
Special: This feat may be taken multiple times. Every time it is taken, a different bioweapon is chosen from the table.
Bioweapons can originate from any predetermined part of your body, such as the mouth, a limb or some other extremity or organ. Most bioweapons are offensive extraordinary abilities, although a certain few are psionic in nature.
Bioweapons require no attack rolls, but they are projected in either a 20-foot line or a 10-foot cone. The range of the bioweapon increases by 10 feet (line) or 5 feet (cone) for every 5 HD you have. Using a bioweapon is a standard action that does not provoke attacks of opportunity. If your bioweapon produces a substance like acid, gas or poison, you are immune to its effects.
Bioweapons draw upon your bio-energy. Every use of the bioweapon expends 1 charge.
Bioweapon damage is measured in damage dice (dX), starting out at 2dX at 1 HD, becoming 3dX at 2 HD, and increasing by +1dX at every odd HD after 1st. (4dX at 3rd, 5dX at 5th, to a maximum of 12dX at 19th). The particular damage die type for any such bioweapon is listed between parentheses in the 'Damage Type' column in Table: Bioweapons.
A bioweapon save DC is Constitution-based if extraordinary, or Intelligence-based if psionic. Psionic bioweapons ignore line of effect and require a Will save for half damage.
