By means of this spell the caster calls upon the power of the earth and stone to defend them and bolster their attacks.  The caster becomes shod in solid rock with spikes jutting from their surface.  The caster gains a +6 Shield bonus to their armor class and DR 10/adamantium.  Further, any creature attacking the caster in melee without the benefit of reach will suffer 1d6 points of damage and receive ongoing bleed damage [2 points] until affected by a successful Heal check [DC 15] or healing effect.  
The caster also becomes extremely potent in melee combat gaining a +4 bonus to their Strength and a +6 to their Constitution score, but suffering a -4 to their Dexterity score.  The caster's movement is also reduced by 5 ft. during the duration of the spell.  All unarmed attacks made by the caster deal lethal damage and deal damage as if one size larger; inflicting the above bleed damage on successful hits [does not stack].  
The spell lasts for 1 round per level of the caster or until the spell has deflected 10 points of damage per level of the caster [maximum 150].
