Valmont's Afterimages

When you cast this spell, a brilliant wave of energy washes over creatures in a 60 feet radius originating from you. Choose up to six willing creatures within range. Until the spell ends, the chosen creatures' movements and actions seem to create a series of afterimages, with a slight delay, and with varying colors.

When the spell is cast,  each affected creature seems to produce eight different images. A creature with at least two active afterimages imposes disadvantage on attacks from other creatures, as the mirroring movements make them harder to hit.

While a creature has at least one active afterimage, they may consume them in different ways, as described below:

• Mirrored Attack. If the creature has taken the attack action, it may make one additional weapon attack as part of the same action, as one of the afterimages gains semi-reality. This attack uses the same attributes and bonuses as the attack(s) the creature made as part of their attack action, and deals an additional 1d8 damage of the creature's choice of fire, cold, or acid damage, as a red, blue, or green afterimage, respectively, performs the attack. The afterimage then disappears.
• Mirrored Spell. If the creature casts a spell, it may alter it depending on the spell's parameters.
  
  • Twinning. When the creature casts a spell that targets only one creature and doesn’t have a range of self, it can spend a number of afterimages equal to the spell’s level to target a second creature in range with the same spell, as an afterimage repeats their casting to the second target. To be eligible, a spell must be incapable of targeting more than one creature at the spell’s current level.
  • Heightening. When the creature casts a spell that forces a creature to make a saving throw to resist its Effects, it can spend three afterimages to give one target of the spell disadvantage on its first saving throw made against the spell, as the afterimage bolsters the creature's casting of the spell.
  • Empowering. When the creature casts a spell that deals damage or heals, it can spend one afterimage to add 1d8 to the damage or healing of the spell, to a maximum of 4d8 increased damage or healing.
