Black Dragon Rune

When you or a creature you can see within 30
feet of you is hit by an attack roll, you can use
your reaction to invoke the rune and choose a
different creature within 30 feet of you, other
than the attacker. The chosen creature becomes
the target of the attack, using the same roll. This
magic can transfer the attack's effects regardless
of the attack's range. Once you invoke this rune,
you can't do so again until you finish a short or
long rest.
