Player > Weapon > Range > Hydra cannon, asp-series
Damage: 4d6 E & F
Range: 30 ft.
Capacity: 20 charges
Special: Blast, shape 3, unwieldy
Rather than firing a single burst of plasma, a hydra cannon generates countless discrete plasma filaments that spread outward in a pattern reminiscent of crawling serpents. The spread of these filaments can be somewhat controlled, allowing a proficient user to avoid hitting a limited number of creatures within the weapon’s area of effect. Python-series hydra cannons offer the least control, while viper-series, asp-series, and cobraseries hydra cannons offer increasingly fine-tuned control over their target areas.

This weapon fires in a cone that extends only to its first range increment. You can’t use it to attack creatures beyond that range.
For each attack you make with a weapon with the blast special property, roll one attack against each target in the cone, starting with those closest to you. Each attack takes a –2 penalty in addition to other penalties, such as the penalty to all attacks during a full attack. Roll damage only once for all targets. If you roll one or more critical hits, roll the extra critical damage only once (or any other special effects on a critical hit that require you to roll) and apply it to each creature against which you score a critical hit. You can’t avoid shooting at allies in the cone, nor can you shoot any creature more than once.
Attacks with blast weapons ignore concealment. A blast weapon doesn’t benefit from feats or abilities that increase the damage of a single attack (such as the operative’s trick attack). Ammunition for blast weapons is designed for blast attacks, so you spend the usage amount only once for each cone of attacks.
Weapons with the unwieldy special property are large and awkward, can’t be fired without cooling down first, or are otherwise difficult to use with repeated attacks. You can’t use an unwieldy weapon as part of a full attack (or any other action in which you could make multiple attacks), you can’t attack with it more than once per round, and you can’t use it to make an attack of opportunity.
A weapon with the shape special property has a complex targeting array that allows it to target specified areas. If you make a single attack as a full action with such a weapon, you can exclude the listed number of squares from within this weapon’s area of effect. This means you can avoid shooting an ally in the area of a blast weapon’s effect, for example.
