暗影后裔（Umbral scions）出处《阴影血脉》（Blood of Shadows pg. 19）第19页暗影后裔是那些能够熟练地控制自己特别强大的暗影遗产的术士。大多数暗影后裔来自黑暗之地。
血统：暗影后裔必须具有暗影（Shadow）【APG】血统。
弱化施法：暗影后裔在每个法术等级上比正常术士少一个法术位。如果这将某个等级的法术位减少到0，那么只有在他的魅力调整给予他这个等级额外法术位的情况下他才能施放这个等级的法术。
这调整了术士的法术。笼罩咒语（Su）：每当暗影后裔施放法术时，就会被一缕阴影笼罩。对本影后裔施放的法术进行法术辨识DC增加2。如果该法术是在昏暗光线或黑暗区域施放的，则DC会增加5。
黑暗侵占（Su）：暗影后裔能够影响她周围的光线。使用标准动作，她可以以30英尺内的生物或物体为中心制作一个10英尺半径的面纱。这层面纱将光照水平降低一级，持续轮数等同于暗影后裔的魅力调整值。在第7级，面纱的半径增加到30英尺。在第8级，面纱将光照水平降低两级。如果光线水平在黑暗之后降低，则将面纱视为深幽黑暗术一样运作。在第14级时，面纱半径增加到60英尺，并赋予其中的任何生物掩护（即使是通常能够穿透完全黑暗的感官，例如黑暗视线能力）。一个暗影后裔每天可以使用这个技能的次数，等于3+她的魅力调整值。
该能力取代了暗影后裔的血统力量。强效暗影（Su）：在第7级，当一个暗影后裔在昏暗或黑暗区域内施放暗影子学派的法术或带有黑暗或阴影（UM）描述符的法术时，她会将她的施法者等级视为提高1级。只需要暗影后裔本人需要处于昏暗或黑暗中。在7级及之后每4级该加值+1，最多在第19级时+4。
该能力取代7级获得的血统专长。致残暗影（Su）：在13级时，当一个暗影后裔用暗影子学派的法术或带有黑暗或暗影描述符的法术瞄准昏暗或黑暗区域内的生物时，该法术的DC会加1。此加成在18级时再加1。
该能力取代13级获得的血统专长。原文：

Umbral Scion
Source Blood of Shadows pg. 19
Umbral scions are sorcerers who are able to expertly control their especially potent shadow heritage. The majority of umbral sorcerers hail from the Darklands.
Bloodline: An umbral scion must have the shadowAPG bloodline.
Diminished Spellcasting: An umbral scion can cast one fewer spell per day of each level than normal. If this reduces the number to 0, she can cast spells of that level only if her Charisma score grants her bonus spells of that level.
This ability alters the sorcerer’s spellcasting.
Shrouded Spells (Su): An umbral scion is enveloped by wisps of shadow whenever she casts a spell. The DC to identify spells cast by an umbral scion increases by 2. If the spell is being cast within an area of dim light or darkness, the DC increases by 5 instead.
Encroaching Darkness (Su): An umbral scion is capable of influencing light around her. As a standard action, she can produce a 10-foot-radius veil centered on a creature or object within 30 feet. This veil decreases the light level by one step and remains for a number of rounds equal to the sorcerer’s Charisma modifier. At 7th level, the veil increases to a 30-foot radius. At 8th level, the veil decreases the light level by two steps. If the light level is decreased past darkness, the veil is treated as deeper darkness. At 14th level, the veil increases to 60 feet and grants any creature within it cover (even against senses normally able to penetrate total darkness, such as the see in darkness ability). An umbral scion can use this ability a number of times per day equal to 3 + her Charisma modifier.
This ability replaces the shadowstrike bloodline power.
Potent Shadows (Su): At 7th level, when an umbral scion casts a spell of the shadow subschool or a spell with the darkness or shadowUM descriptor within an area of dim light or darkness, she treats her caster level as 1 higher. Only the sorcerer herself needs to be in dim light or darkness. This bonus increases by 1 every 4 sorcerer levels beyond 7th she has to a maximum of +4 at 19th level.
This ability replaces the 7th-level bloodline feat.
Crippling Darkness (Su): At 13th level, when an umbral scion targets a creature within an area of dim light or darkness with a spell of the shadow subschool or a spell with the darkness or shadowUM descriptor, the DC for the spell increases by 1. This bonus increases by 1 at 18th level.
This ability replaces the 13th-level bloodline feat.
