Shattered Soul

Shabti who are killed are exceptionally difficult to return to life. Those who attempt to return a shabti to life using raise dead, resurrection, or similar spells must succeed at a caster level check equal to 10 + the shabti's Hit Dice. If this check fails, the spell fails and the caster can't return the shabti to life for the next 24 hours (though the caster can try again after this period).
