Bellicose

You project aggressive behaviour, either because you want to protect your allies, or because you crave hostile conflicts. Either way, you have a natural willingness to fight. When you take this feat, you get the following benefits:

• When you roll Initiative, you can get d20 + Constitution modifier temporary hit points. You can use this feature once per short or long rest.
• When you reduce a hostile creature to 0 hit points, you can use your reaction to move up to half your speed in a hostile creature's direction.
• If you roll for an attack against a creature that hasn't taken its turn in combat yet or hasn't received any damage from you or any of your allies, you get advantage on the first attack you make against this target. The attack does an extra 1d4 damage of your weapon's type on a hit.
