Grisald's will reanimate a corpse to protect the caster. The corpse is used as the target for the spell, and must be of human origin. The skeleton will continue to protect the caster as would a normal bodyguard for the duration of the spell, or until it is killed. The duration is fairly significant, but it is only possible to summon one skeleton at a time, regardless of skill.

The skeleton summoned will use whatever weapons or armour was on the corpse before its reanimation, whether those were used by the original subject, or added by the caster afterwards. After it perishes, again, any items will be dropped. For best effect, the caster can and should shield the skeleton using Transcendent Pneumatic Alleviator.

 

This spell can prove to be a very useful fourth main defensive spell for wizards with enough spare memory for the spell and a willingness to share at least some of your experience.
