Constructed

For the purposes of effects targeting creatures by type (such as a ranger's favored enemy and bane weapons), androids count as both humanoids and constructs. Androids gain a +4 racial bonus on all saving throws against mind-affecting effects, paralysis, poison, and stun effects, are not subject to fatigue or exhaustion, and are immune to disease and sleep effects. Androids can never gain morale bonuses, and are immune to fear effects and all emotion-based effects.
