Damage
From PSU Cyril Wiki
This is the number that appears on either a player or a monster/creature. Damage can be dealth with weapons and certain status effects.
However if the player reaches a certain defence low leveled monsters will not be able to do any damage on the player, a 0 will ALWAYS appear.
Sometimes a player blocks the damage of the enemy resulting in a zero hit aswell (which can be counter attacked to proform a critical attack which causes 150% of the normal ATP for the next attack)
Monsters can also ignore a players damage due to low accuracy or low ATP.
