Empower Creature

You tap a creature (or yourself), and tell them a (motivational or jibe) to empower them. The targeted creature gains: advantage on all strength based attack rolls and saving throws, 15ft in extra movement, and immunity to all damage except for psychic(magical or not). But, after the spell ends, they fall prone, gain 1 level in exhaustion, and take all of the negated damage.(If the damage would kill the creature immediately they instead fail 2 death saves).

When used with a spell slot of a higher level than 2nd level, the duration increases by 1 turn for every level above 2nd level
