Immense Defence is a shield technique in the Dragon Quest series. It increases the frequency of blocking attacks.
This ability is learned with 32 skill points allocated into the Shield skill.
Acting the same as in IX, the skill is learned with 15 skill points allocated into the Shield skill. Monsters that use it are the Grim grinners, and Bad karmours. Harmours can learn it once players recruit one.
Hendrik will learn the skill via his shield path, for 6 points. It costs 3 MP to use and will raise his base blocking chance by 50% for two turns.
