Mirrorlight Edge

Damage: 1d8 (V:1d10) Slashing + 1d4 Force
Modifier: Melee Attacks +1, Melee Damage +1
Once per day, as an action, you can command
the Magical Longsword to emit up to 2 ghostly
projections of itself which emit a phosphorescent
blue light and last until dismissed or you
complete a long rest. Each projection adds +1 to
melee damage rolls. However, each time an attack
with this weapon misses, a projection dissipates.
Requires Attunement.
