I like this idea. Let’s keep it going!
Hostility
1st-level enchantment
Casting Time:1 action
Range:30 feet
Components: V, S
Duration: concentration, up to one minute
You attempt to enrage a humanoid you can see within range. It must make a Wisdom saving throw. If it fails the saving throw, it treats all creatures it can see as hostile until the spell ends. Each round at the start of its turn, it can attempt another Wisdom saving throw to end the spell.
