The 7 God's Requiem

The God's may be gone, but their legend echoes in the halls of eternity. The tales of their might has been sung by the bards and minstrels for generations.

The spell lasts for 7 turns, each turn something different happens.

Turn 1: Any creature that deals damage to you takes fire damage equal to the damage dealt to you times 1.5

Turn 2:  Any melee damage you deal is multiplied by 1.5

Turn 3: Any spell damage you deal is multiplied by 1.5

Turn 4: your AC increases by 3

Turn 5: and healing you do is doubled

Turn 6: you take double damage but deal double damage

Turn 7: you deal triple damage and can attack twice but at the end of the turn you drop to 0 hit points

Whenever battle ends, so does the spell on whatever turn you are at.
