Soul Ward (Su) wrote:
An intangible field of siphoned soul energy protects a ravener from destruction. This ward has a maximum number of hit points equal to twice the ravener’s Hit Dice, but starts at half this amount. Whenever a ravener would be reduced below 1 hit point, all damage in excess of that which would reduce it to 1 hit point is instead dealt to its soul ward. If this damage reduces the soul ward to fewer than 0 hit points, the ravener is destroyed.

A ravener retains the base creature’s spellcasting capability, adding three levels to the base creature’s caster level. This increases the number of spells known by the ravener, but the ravener loses all spell slots. Instead, whenever the ravener wishes to cast any one of its spells known, it consumes a number of hit points from its soul ward equal to the spell slot level necessary to cast the spell (including increased levels for metamagic feats and so on). If the soul ward has insufficient hit points, the ravener cannot cast that spell. Casting a spell that reduces its soul ward to exactly 0 hit points does not harm the ravener (though most are not comfortable without this buffer of soul-energy and try to replenish it quickly).
