GURPSよろず

　超幸運 is difficult to explain as anything other than a limited degree of control over reality. This capability is traditional for gods and powerful spirits. Among mortals, only the most gifted psis, supers, and wizards are likely to possess it.
The GM probably shouldn’t allow this trait outside of cinematic action games, as it’s thoroughly unrealistic and tends to short-circuit mystery and suspense. On the other hand, if the PCs are demigods, the GM might permit higher levels: 超幸運 2 [200] works every 30 minutes, 超幸運 3 [300] works every 15 minutes, and so on, with each level halving the time between uses.

■代替案（Alternatives）
Most lucky heroes should just use 幸運 (p. 59) --or 都合のいい偶然 (p. 73), if their luck doesn’t lend itself to interpretation as “good odds.” Those who can consciously load the dice in their favor but not guarantee success have 「視覚化暗示」 (p. 87).

■追加特別増強（New Special Enhancement）s
Alter Reality:
　Your 超幸運 works retroactively. You can wait until after you roll and then specify a different result, altering the past.
You must declare this immediately. Once you or anyone else has made another roll, the flow of time becomes too complex for you to unravel.
Alter Reality always produces visible effects; e.g., time rewinds and replays differently, or a glowing hand reaches down from the heavens and changes things. +75%.

Wishing: You can specify the result of any die roll made in your presence.
You must personally witness the action you wish to influence. Normal usage limits apply. +100% if you can affect your rolls and those of others; +0% if you can aid others but not yourself.

■パワーアップ（Powering Up）
超幸運 is a perfect fit for cosmic and divine powers. Other options are a magical power, a psionic probability- control power, or even a spirit power, if the user commands spirits that have 超幸運 with Wishing.
The GM should consider restricting Alter Reality and Wishing (and higher levels of 「超幸運」, if allowed) to cosmic powers --although Alter Reality might fit less-than-cosmic time-control powers.
才能 gives a bonus to die rolls manipulated by this ability. Since the user can dictate outcomes, the practical effect is to alter margin of success or failure, or extend the range of possible results (e.g., for damage rolls).
