OXY.
When you finally break the mountain top, rise up above and break the threshold, a final ring just down the track... You call your companion back from her idiocy, race forward, and release your drug magic on whoever might be near to you. And, when you look down, you find that your hooves are no longer cloven, but again solid plates of blackness. Your body is huge again, your muscles returned, your horseshoes clattering noisily against the stone. You dig and and run forward, hoping your drug magic will slow down those around you. Onward you go to the end, body sweating with the effort of your leaping and running.
Please do not tag Oxy unless it is in an opening post
