You throw a magical card, which creates a beam of crackling energy that streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, roll a d6. The spell's effect resolves based on the result:
1. Red: The target takes 1d10 + your spellcasting ability modifier fire damage.
2. Orange: The target takes 1d10 + your spellcasting ability modifier acid damage.
3. Yellow: The target takes 1d10 + your spellcasting ability modifier lightning damage.
4. Green: The target takes 1d10 + your spellcasting ability modifier poison damage.
5. Blue: The target takes 1d10 + your spellcasting ability modifier cold damage
6. Violet: The target takes 1d10 psychic damage and must succeed on a Constitution saving throw or become blinded until the end of their next turn.
You may throw multiple cards at once when you reach higher levels: two cards at 5th level, three cards at 11th level, and four cards at 17th level. You can direct the cards at the same target or at different ones. Make a separate attack roll for each card.
