Supreme Strength (3.5e Epic Feat)
From D&D Wiki
Supreme Strength [Epic, General]
Due to unusual body structure, paranormal heritage or magical/surgical enhancement, you can activate your physical strength in much impressive way than usual.
Prerequisite: The character cannot be an ordinary, pure-blooded mortal.
Benefit: You can lift, push and drag twice the usual weight for your size and strength score (your carrying capability is doubled) and gain a +3 bonus on all Strength-based checks. However, your raw physical strength (your strength score) is untouched.
Normal: You don't possess those benefits.
Special: This feat can be taken only in the creation of the character, when the character gains a template, or if the character is magically/surgically enhanced.
