An aspiration is a quick prayer on the
order of, "Give me strength!" or "Don?t let
me goof up!" In game terms, it permits a
nervous player to pre-roll a dice roll. The
player-caster rolls a d20 out of the player's
own sight for the DM, who records it. At
any time during the next game hour, the
caster may appeal to have a bad die roll
replaced by the hidden roll. The d20 can be
applied as a "to hit" roll, a saving throw,
or, by multiplying it by live, a percentile
dice roll. Upon the caster's request, whatever
was rolled in casting the orison is revealed,
and becomes the official dice roll.
There is no guarantee that the previous roll
will be better, but it will be a second chance.
The somatic component is the caster's ritual
sign.
