Arboreal Immurement

Regular; Resisted by HT 
Similar to Entombment, except that a tree, instead of the earth, confines the subject. The subject is instantly swallowed by the nearest tree large enough to contain him. He remains in Suspended Animation in a tiny cylindrical chamber inside the tree, until rescued by chopping through the tree or the cancellation of the spell. 
A mage who casts Arboreal Immurement on himself may elect to stay awake, but this is unwise unless he can create air!

Modifiers: Apply the long-distance modifier for the distance from the subject to the nearest tree large enough to hold him.
