Deftness

Deftness (きようさ) measures the ability of a character to steal an item from an enemy, as well as controlling how frequently a character may perform a critical hit, performing preemptive strikes on enemies, and the ability to escape from battle.

Dragon Quest IX: Sentinels of the Starry Skies

Steal rate is calculated as:

Critical Hit rate is calculated as Deftness/100 + 3% (with weapon skill trait boost). Wearing the Critical Acclaim will add another 4%, and thus the maximum rate is 16.99% at 999 deftness.

Dragon Quest X

Currently unknown.

Dragon Quest XI: Echoes of an Elusive Age

Erik's steal rate is calculated as Deftness/20, meaning that every 20 points will increase his chance for success by 1%. With his guile bonuses this brings the maximum rate to 75%.

Similarly, the critical hit rate is calculated as Deftness/200, which limits the natural cap to 5%.

Any character can consume a seed of deftness to increase this attribute.
