Replaces: Inspire Courage
An archivist who has identified a creature with a Knowledge check appropriate to its type can use performance to share strategies for defeating it with allies in combat. The archivist and any allies within 30 feet gain a +1 insight bonus to AC and on attack rolls and saving throws against exceptional, supernatural, and spell-like abilities used by creatures of that specific kind of monster (e.g., frost giants, not all giants or all humanoids). This bonus increases by +1 at 5th level and every six levels thereafter. This language-dependent ability requires visual and audible components. This ability replaces inspire courage.
