Defense Percent

Percent of incoming damage reduced. Defense % is applied before defense absolute.

In most Defense builds, Defense % if one of the main stats, since it lowers the incoming damage by a % making it first layer of defense, effectively increasing Effective HP and significantly boosting Tower survivability.

Using the defense % lab, the Extra Def card and Defense % perk, defense percent can reach 95.5% however, there is a limit of 98%.

Chrono Field Damage Reduction is separate from def % and does not count toward the 98% limit.
