|Casting time:||1 action|
You call upon the echo of a spell just cast. You call upon the reflection of a spell, spell-like ability, or mystery cast within the last round. Both the caster and the effect must be within the spells range. You cast the spell at whatever spell level it was cast, choosing new targets or effects as applicable and as the original spell would allow. You use your spellcasting ability to determine save DCs and attack rolls. You cannot echo a spell cast using a spell slot above 4th level.
At Higher Levels. When you cast this spell using a spell slot of 6th or higher you may add 1 to the maximum spell slot the spell you are echoing was cast with for each two spell slots used over 4th.
If you have mastery of the Black Magic path, you may echo a spell, spell-like ability, or mystery cast within the last two rounds.
