Idea №27 RWBY x Worm
So, no matter how shitty Volume 7 of RWBY turned out to be (not that it was unexpected or anything), after the introduction of a new (wasted) character, Clover, and reveal of his Good Luck semblance I got an idea for this Alt Power Taylor.
Taylor's ability can be described as "luck" manipulation.
Shaker/Thinker (+Trump/Master subcategories) - Taylor can sense just how much negative and positive "luck" any item or person in her range has, and she can collect and redistribute that luck. There is no upper limit on how much luck she can hold on to herself, or force onto someone or something else. The speed at which she can drain or redistribute luck decreases with distance. Whatever luck the target has lost will slowly be restored over time. The restoration of peoples luck is influenced by their actions, choices, places and people around them. The restoration of items luck is influenced only by peoples luck and actions. Taylor can "bless" or "curse" people and items by completely draining them of either positive or negative luck, the curse or blessing then can be further enhanced with positive or negative luck. Possible Trump and Master subcategories due to the uncertainty of how exactly Taylors powers influence the probabilities and cause her power interferes with precognition type powers. Overall the power itself is similar to Bastard Son's power, except that it's a bit more nuanced and less obvious.
Thinker/Master (self) - Taylor has a vague feeling of how likely is her immediate next action to succeed and can use a bit of positive luck (if she has any at the time) to increase her chances.
Taylor, just like everyone else, can create her own luck through her actions, but she can also absorb and/or enhance it with the luck that she has collected.
The effect of luck on items and people is multiplicative to their characteristics, abilities and skills.
