Damage is the abuse that has been dealt to a particular target. HP or Hit Points represent how much damage a player, monster, or non-player character, can take before falling unconscious or dying (see K.O.)
Type of Damage
There are two types of damage: Physical and Magical.
The percentage values listed on these items are only partially correct. The formula to determine the exact damage reduction is:
[(Percentage listed on item * 256) Rounded down] / 256
Example: Earth/Terra's Staff is listed as -20% physical damage taken.
20% * 256 = 51.2
51.2 rounded down is 51
51/256 = 0.19921875
Actual reduction = 19.921875%
Damage reduction caps out at 128/256 (50%).
Physical Damage is defined as damage dealt to players, monsters or non-player characters from a physical source, such as a monster stabbing you with a knife. Other sources could include damage from area attacks, usually Jumping attacks, or attacks which involve monsters smashing their bodies into you. Overall physical damage is resisted/reduced by one's Defense and Vitality.
Magical damage is defined as damage dealt to players, monsters or non-player characters from a magical source, such as a player casting Stonega IV on a monster. Other sources can sometimes include damage from area attacks, usually grenade blasts or other explosive abilities, or attacks which deal Damage Over Time. (Sometimes area attacks can be considered nonmagical nonphysical though and are not bound by these rules, but may still correlate to an element and may have damage reduced through elemental defense such as Barfire) Overall magic damage is resisted/reduced by one's Magic Defense, Intelligence, and Mind.
Breath damage is not physical or Magical, but can sometimes correlate to a specific element, so reduction in Breath damage is commonly through spells like Barfire or Baraero, Breath damage reduction is also available through BLU magic traits, Atmas, and a very limited amount of equipments.
