Residual Fold contamination: -2 Will and -2 attack/skills (dread), Will save each interval or manifest a phenomenon/gain corruption.
A fold-touched character carries a smear of the Fold on them -- brushed by
unshielded Fold exposure, caught in a Fold Cascade, or partially failed
a Fold Catastrophe save. The contamination shows as dread: -2 on Will saves
and -2 on attack and skill rolls. At each interval (every round in a Fold
tide, otherwise once per day) they make a Will save (DC 12 + exposure level);
failure manifests a minor Fold phenomenon or grants a point of lasting
corruption. The acute form is Dread -- raw psychic horror in which the
character is Panicked by the void around them; failing the Dread Will save by
5 or more leaves the character Fold-Touched long after the source has passed.
The contamination fades with time spent behind Fold shielding, with a
Sanctioning rite, or with steady successful Will saves. Blanks and the
properly warded feel nothing at all.
