Bond of Antaios (3.5e Maneuver)

''You channel the spirit of the giant Antaios. You will be unbeatable as long as you are in contact with mother earth.''

While in this stance you gain 1 temporary hit point per initiator level you have which refreshes at the beginning of your turn, as long as you are in contact with unworked earth, stone, and other minerals. If you are on worked or man-made materials you gain -5 less temporary hp and if airborne, you gain -10 less temporary hp (minimum 0 for both). Temporary hit points overlap, they do not stack. However, temporary hp gained from the Stone PowerToB feat does stack.
