Arxan's Hatred

Filling yourself with a blinded rage, you become a frenzying force of fury and murder. For the spell’s duration, you gain the following benefits: 

Each melee weapon attack you make deals additional damage equal to your spellcasting ability modifier. 

You are immune to being Charmed or Frightened and have advantage on all Wisdom Saving throws. 

When you reduce a creature to 0 hit points with a melee weapon attack, you may make another melee weapon attack as a bonus action. 

If you have dealt damage on your turn, you gain temporary hit points equal to your spellcasting ability modifier at the end of your turn. 

If you do not attack a creature on your turn, or haven’t taken damage since your last turn, the spell ends.
