Innate Divination.

Pythia can cast augury, divination, and commune at will, requiring no components. These spells are flavored as prophetic trance states.

Oracle’s Trance (Recharge 5–6).

As an action, Pythia enters a trance for 1 minute. While in this state:

• She has advantage on all Wisdom and Charisma saving throws.

• She can’t be surprised.

• Once per turn, she can force a creature she can see within 60 feet to reroll an attack, saving throw, or ability check. They must use the new result.

Prophetic Utterance (1/day).

Pythia speaks a truth from the gods. The DM may give the party a cryptic but accurate vision of a major future event. Mechanically, this functions as a legend lore combined with foresight for one creature for 1 hour.
