Death pact

The caster makes a pack with a being (dm's choice) which the target has agreed to, the targets constitution is reduced by 2 as the price permanently until the spell is used and the diamond is consumed during the  casting. When the target dies this spell triggers and the following things happen in the order listed:

1. The targets body is transported to a place decided by the caster at the time of casting.
2. The target is resurrected via the spell raise dead.   
3. The target is healed via the spell heal.

If the body is not usable such as it being disintegrated/the raise dead spell doesn't work then the spell fails.
