Interstellar Species
Rulebook

Classes
Conflict drives innovation, and in a strange and dangerous galaxy you’ve unlocked unparalleled means to adapt. By embracing mystic tradition, extensive augmentation, deliberate genetic mutation, or relying on other extraordinary means, you transform yourself into a powerful being better suited to achieving your goals. You might adopt characteristics of a ferocious chimera, an undead scion, a cybernetic paragon, or anything in between. Yet your evolution boasts a will of its own. Your abilities fight you for control in stressful situations, even while providing lethal instincts, an innate weapon, and spontaneous adaptations that help you outmaneuver, outwit, and outmatch your foes. No matter your niche, you are an adaptable combatant who forges your destiny in flesh, bone, or steel.

Drone Mods
As a standard action, you create a devastating energy stream that arcs between your custom rig and your drone, creating a line effect; to use this ability, your custom rig must be in your possession and your drone must be within 30 feet of you. For each advanced drone mod your drone has, the arc deals 1d8 electricity damage to each creature in the line; affected creatures can attempt Reflex saving throws to halve the damage (DC = 10 + half your mechanic level + your Intelligence modifier). The damage increases by 1d8 at 4th level and every three levels thereafter. You can instead activate this ability as a full action to increase the damage dice to d10s. Once you’ve activated this drone mod, you can’t do so again until you’ve rested for 10 minutes to regain Stamina Points.
Your drone conducts, stores, and unleashes electricity with a touch. Your drone gains a special unarmed strike that deals 1d3 electricity damage; this attack doesn’t count as archaic and targets EAC. When your drone reaches 3rd level, it gains Weapon Specialization with its natural weapon. Your drone must have the resistance (electricity) mod to select this mod.
Advanced
By periodically scavenging materials, your drone creates improvised explosives. After a full 8 hour rest, your drone can create up to three grenades by spending 2 Resolve Points per grenade. It can create any grenade with an item level that doesn’t exceed your mechanic level – 3, but only the drone can use them. These grenades remain functional until used or until the drone recovers Resolve Points after a full 8 hour rest. The drone can draw and throw one of these grenades as a standard action, even if it lacks the limbs to do so. As a reaction when your drone is reduced to 0 HP, it can detonate one of its stored grenades, which explodes using one corner of the drone’s space as the explosion’s grid intersection. You can select this mod a second time, which reduces the RP cost per grenade to 1 and enables the drone to make any grenade with an item level less than your mechanic level.
When your drone becomes grappled or is dealt damage by a creature within its reach, your drone can shock the attacker, dealing electricity damage as if the drone had struck the attacker with its conductive plating attack. Once your drone has used this mod, it can’t use it again for 1d4 rounds. Your drone must have the conductive plating mod to select this mod.
Drone Chassis
Compact and resilient, the stormscout drone was developed on Shimrinsara to survive deadly weather and even direct lightning strikes—defenses that make them popular across the galaxy for entering dangerous areas, collecting samples for scientific examination, and recording their surroundings.
SizeMedium
Reinforced to shrug off falling debris and rescue cave-in victims, the tunnel drone uses a combination of digging apparatuses, sensors, and heavy limbs to detect, access, and (if necessary) subdue subterranean objectives.

Despite their size, linnormlings claim to be descendants of the Eldest Ragadahn. They’re willful creatures yet offer their expertise with curses to anyone offering them proper tribute.
Water elementals are common on Kalo-Mahoi, and the longer they remain on the Material Plane, the more they tend to adapt, taking on a semipermanent shape. While this diminishes some of the elemental’s resistances, it also drives them to imprint on and work with other creatures, such as kalos.

Resembling a five-eyed manta ray, a Mahoi manta is the traditional kalo mount and beast of burden. Mahoi mantas forge strong bonds with their favorite riders and range in color from pale greys and blues to black, with a rare few being pale pink or purple.
