Mystic Might is a prayer that gives 6 bonus levels to a player's Magic skill when calculating hit chance. It cannot be used in conjunction with any of the other prayers that provide a magic, ranged, attack, or strength bonus. It replaces Mystic Lore when unlocked. It is the best magical accuracy prayer in free-to-play and is the final prayer to which non-Members have access. Members' Augury provides a better magical enhancement, however.
When a player gets 45 Prayer, the message they get calls the prayer "Magic Might."
