At 20th level, a storyteller gains the ability to sweep others away into a story of his own making. He must perform for 1 full round, telling a tale to set the snare for his living story and spending 1 round of his storyteller's performance. At the end of that round, he can affect up to 30 Hit Dice of listeners within range with microcosm*. Unlike with a normal microcosm, this is also a sonic and language-dependent ability, and a creature with 16 or more Hit Dice that succeeds at its save is immune to the storyteller's living story ability for 24 hours.
This ability replaces astral beacon.
