Hyper Strength

Hyper strength [Minor] by Iczer

'I swear boss, he just kept getting stronger'

The character is stronger than most, and gets stronger and stronger while he is opposed.
His PS increases by 10 and moves to extraordinary in lifting and carrying capacity.
Moreso, when confronted by a stronger opponent, the character gains +2 PS every round until he is stronger. A stronger opponent is any living foe whose PS exceeds his own (numerically). Actual strength category is irrelevant.
As a final burst of strength, the character can sacrafice his PE score to enhance his PS further. By doing so, his PS increases by an amount of PE sacraficed and jumps to superhuman in lifting and carrying. He loses a like amount of Hitpoints by doing so. The extra PS fades after one melee round per level. The PE returns after 12 hours of rest.
