以太 Defence is a stat which reduces the amount of damage received from 以太 attacks.
Characters' 以太 Defence
The damage that characters receive from 以太 attacks is reduced by the amount of their 以太 defence. An 以太 defence of 1,000 will reduce 以太 attacks by 1,000 points of damage.
If 以太 defence is greater than or equal to the attack's 以太 damage, the character will receive only 1 point of damage, or 0 if they block the attack.
敌人' 以太 Defence
Unlike characters, an enemy's 以太 defence stat is a percentage and has a direction. 以太 attacks from that direction will have the damage reduced by the specified percentage. The enemy's 以太 defence in 其它 directions is zero. Most 敌人 have an 以太 defence of zero in all directions, and receive the full amount of damage from 以太 attacks unless the attack is blocked.
For example, the Blizzard Belgazas has an 以太 defence of 30 to the front and rear, which reduces 以太 damage from those directions by 30%, while 以太 damage from the sides will not be reduced.
The 以太 Def Down debuff will reduce an enemy's 以太 defence by the specified amount. If the result is less than zero, the 敌人 will take extra damage from 以太 attacks. For example, if Blizzard Belgazas is hit by an 以太 Def Down of 25%, its 以太 defence to the front and rear will be reduced from 30 to 5; its 以太 defence to the sides will be reduced from 0 to -25, causing it to take an extra 25% damage from 以太 attacks on its sides.
