Temporary Revival

You touch a creature that has been dead for no longer than 200 years and that died for any reason except old age. If the creature's soul is free and willing, the creature is restored to life with half of it's max hit points(rounded down). This spell closes all wounds, but does not neutralizes poisons, cure diseases, or lift any curses affecting the creature when it died. The spell fixes damaged organs and limbs. The spell automatically fails against undead creatures.

The creature's body must be present in order for the spell to succeed. If the spell is successful, the creature remains alive for 1d4 weeks. After that, the creature goes to sleep and dies peacefully. The creature can still die of old age. A creature brought to life by this spell can still be targeted by revival spells(i.e. Raise Dead, Resurrection, True Resurrection).

At Higher Levels. If the spell is cast at 5th level, the creatures stays alive for 1d6 months. If the spell is cast at 7th level, the creature stays alive for 1d8 years. If the spell is cast at 8th level, the creature stays alive for 1d10 decades.
