GURPSよろず

see p. B41
「チャネリング」 normally lets the user serve as a conduit to the spirit world, but the GM may permit variant forms that enable contact with the dream world, the past, parallel universes, cyberspace, etc., instead. Each form of 「チャネリング」 is a separate advantage.

■代替案（Alternatives）
To speak with spirits, take 「霊媒」 (p. 59). Those who experience possession by a spirit that grants superhuman capabilities should take an 「変身」 (see 「形態変更」, p. 74) --possibly with the 「制御できない」 limitation --that represents their possessed self.

■追加特別増強（New Special Enhancement）
Aware: You remain aware of the world when using your ability, and can move and act normally while spirits speak through you. +50%.

■追加特別限定（New Special Limitation）s
「チャネリング」 often requires a ritual or séance to use. If so, add 「用意必須」 (p. B114). Another limitation is common in many settings:

Specialized:
You can only channel one specific class of spirits.
Possibilities include angels, demons, elementals, faerie, ghosts, and anything else the GM wishes to allow. -50%.

■パワーアップ（Powering Up）
「チャネリング」 suits almost any supernatural power. 「才能」 adds to Will rolls to enter the trance and resist 「憑依」 (or other mental attacks) by channeled entities.
