Strength Negation
Strength Negation: [Minor] by Iczer
'Hey muscles...how you like me now"
The character's body emits a kind of bio-weakness field that saps the strength of others. Anyone in contact with the character while he consciously has this power 'on' finds their PS reduced by 10 +1 per level. Even moreso, PS becomes scaled back to normal human levels when this occurs. Even physical attacks see their damage reduced (barehanded attacks only, melee weapon attacks are OK) seeing strength diminish at the point of impact, and then return as soon as the hand has been removed.
While there is no saving throw per se, there are some limits. It functions only with living beings. supernatural creatures (though not mysticall bestowed or mega heroes) and machines ignore the PS drain. Extraordinary beasts are still affected but creatures made of magic are not.
