S-Tier Unmatched utility and social dominance with guaranteed success on Charisma checks and magical lie detection immunity.

Player Guide

Cast Glibness before any social encounter where persuasion, deception, or intimidation is critical—the guaranteed 15 on Charisma checks ensures near-certain success. Use it defensively against divination magic that detects falsehoods, making you immune to magical interrogation and truth-sensing abilities. The spell's 1-hour duration allows you to maintain it throughout entire adventuring days, making it ideal for infiltration, negotiation, or court intrigue scenarios.

DM Tips

Glibness is incredibly powerful in social-heavy campaigns; consider requiring saving throws for opposed Insight checks or limiting its use in situations where logic should override charm. Remember the spell doesn't grant advantage on checks—it replaces rolls with 15, so a bard with +5 Charisma modifier gets 20, not higher.
