Your eldritch master's influence grows, granting you the following benefits.
Frenzied Ally
When a creature has the Frenzied condition of your Frenzied Strike, it regards you and your Cohort as allies while it has the condition.
Frenzied Blitz
When you use your Blitz feature, you can direct a creature that has the Frenzied condition, even if that creature isn't an ally.
Extended Frenzy
Whenever a creature that has the Frenzied condition of your Frenzied Strike ends its turn, it must make a Wisdom saving throw against your Maneuver save DC. On a failed save, the Frenzied condition doesn't end for that creature. On a success, the condition ends for that creature.
