Prerequisite: Warlock
When you cast a Warlock spell, or use a Mystic Arcanum that requires Concentration, that spell persists for 1 round after you lose Concentration for any reason.
You can still choose to voluntarily end that spell by dropping Concentration.

Posted Apr 2, 2026This only applies to Warlock spells or Mystic Arcana that you cast. Cantrips gained through the Pact of the Tome would be affected, but spells cast via magic items, using spell slots gained from Multiclassing, or spells gained through Feats, or as racial abilities do not benefit from this Invocation.
Yes, this allows the user to cast a spell requiring Concentration, then cast another Concentration spell on the following round, and have both spells active at the same time (for 1 round).
The 1 round limitation, plus the low number of spell slots available to Warlocks, prevent most serious abuses of this Invocation.
