Let the Mage first be expert in the use of Shield and Phantasmal Force, as well as raising and directing energy.
Let him then proceed to enflame himself.
Let him then construct about himself a sphere of a five foot radius, after the manner of a solid wooden shell erected about himself, and also to fill it with the energy of his essence.
Let him color the outside of this shell as he will, to make it more conspicuous or less conspicuous to the observer, as he will.
Let him continue to enflame himself and charge the Hut with his essence, until such time as he no longer requires its protection.
