Shirrens are eager to learn about new cultures and societies. Shirrens receive a +2 racial bonus to Culture and Diplomacy checks.

As long as you have enough time, you can take 20 on Culture checks to recall knowledge, even if you don’t have access to a computer terminal or other means of research.

When you attempt an initial Disguise check, you can forgo rolling your expertise die. Instead, the first time a creature would pierce your disguise with a Perception check, treat its result as if it had rolled a natural 1 on its Perception check. This benefit applies only once per disguise. At 9th level, this ability also applies against the second creature who pierces your disguise.

You have created a customized toolkit you can use to hack systems and items. Your custom rig can be configured to take up an upgrade slot on your armor or can be installed as a cybernetic augmentation system in your brain (though it can be combined with a datajack for the same price as installing a datajack normally), your eyes, or an arm. For more information, see augmentations. Alternatively, you can configure it to be a handheld device, meaning that you must retrieve it and hold it to use it effectively. While using this rig, you always count as having the appropriate tool or basic kit for any Computers or Engineering skill check you attempt. Some mechanic tricks and drone mods require the use of a custom rig. In addition, you can use your custom rig as a Mk I comm unit. Finally, if you have a drone, you can use your custom rig to communicate over an encrypted channel with your drone to issue commands to its AI or directly control it at a range of 2,500 feet.

If your custom rig is damaged, destroyed, lost, or stolen, you can kitbash a new one from any engineering kit, hacking kit, or other technological toolkit, reconfiguring the materials into a new custom rig with 1 hour of work. You can have only one custom rig at a time. If you create a new custom rig, your old one functions as a normal toolkit of whatever type you made it from and can no longer be used with your mechanic tricks.

As a move action, you can draw on the properties of dark matter to increase your density, allowing you to resist physical damage. You gain damage reduction 1/—. This increases to DR 2/— at 6th level and increases by 1 again every 3 solarian levels thereafter. This benefit lasts for 1 round or until you leave graviton mode.

When you are attuned or fully attuned, your DR from dark matter is equal to half your solarian level.

Ysoki can see up to 60 feet in the dark. See page 263 for more information.

For your debilitating trick, you can attempt to temporarily suppress one magic item or deactivate one weapon, piece of equipment, or armor upgrade worn or carried by the target. Roll 1d20 + your operative level; the DC is equal to 10 + the item level. If you succeed, you deactivate the device (or suppress the item’s magical properties) until the beginning of your next turn. The device’s owner can spend a move action and attempt an Engineering check (for technological devices) or a Mysticism check (for magic items) against your operative exploit DC to try to reactivate the device.

You can instead use this debilitating trick to temporarily deactivate a construct that has either the magical subtype (such as a golem) or the technological subtype (such as a robot). You don’t need to attempt a check, but the creature can attempt a Fortitude save to negate the debilitating effect. If it fails, it’s stunned until the beginning of your next turn. Once you’ve used this ability to attempt to deactivate a construct, that creature is immune to your deactivating shot for 24 hours.

Your can strike your enemies’ weak points and deal more damage. D Prerequisites: Base attack bonus +1.

With the deafening fusion, a weapon releases a blast of low- frequency sonic energy on impact. The weapon gains the deafen critical hit effect (see page 182). If the weapon already has a critical hit effect, when you score a critical hit, you can apply either the weapon’s normal critical hit effect or the deafen effect. Only weapons that deal bludgeoning, piercing, slashing, or sonic damage can benefit from a deafening fusion.

When you hit an enemy with a ranged attack or an attack with a weapon with the blast or explode special property, you can spend 1 Resolve Point to inflict a debilitating effect on that enemy for a number of rounds equal to your Strength bonus. You can choose to make the target deafened, flat- footed, or off-target (see pages 275–277), or to reduce its speeds by half (to a minimum of 10 feet). The target can negate this effect with a successful Fortitude save (DC = 10 + half your soldier level + your Strength modifier).
