The bond between an offense/air shifter and a bard is utterly sick. You've got a pair of stoneskinned, hasted, jack'd, resisting'd, (etc bard songs, etc wands & scrolls) asswhoopers coming after you. If the bard gets off "when...," they're all dead unless they run super fast. Even then, with an airform on them they're all just meat.

...and even more other little tidbits from that bond go with it too :)
