Black Lotus Assault

The black lotus only blooms during the solar eclipse, when the nearest star understands its own mortality.
The first time you take the Attack action during your turn, you can cast this spell to summon a swirl of black lotus petals to surround your weapon, distracting your does and enabling you to strike with great power. Each successful hit you make with this weapon before the spell ends, the target must make a Wisdom saving throw or have a new effect apply. Once you've made three weapon attacks, the spell ends. At Higher Levels: When you cast this spell using a spell slot of 2nd-level or higher, the psychic damage of the 2nd hit increases by 1d6 per spell slot above 1st.
 * 1st Hit: If the target fails their saving throw, their movement speed is halved until the end of their next turn.
 * 2nd Hit: If the target fails their saving throw, they take 1d6 psychic damage and cannot take reactions until after the end of your next turn.
 * 3rd Hit: If the target fails their saving throw, they take 2d6 psychic damage and cannot take bonus actions during their next turn.
