Bosses from Lotus to Black Mage has 300% Percentage Damage Reduction (PDR). It is recommended to optimise your IED for 300% PDR even if you are not at battling Lotus, unless you are optimising for Grandis bosses with higher PDR (e.g. Serene has 380%).

Damage % - See from stats window Damage + Boss Damage.

IED % - See from stats window Ignore Def.

Att % - Manually add up from Weapon, Secondary Weapon, Emblem potential lines.

Perform a battle analysis/statistics and note down the damage ratio % of each skills.

Enter the skill name, in-built skill IED (e.g. V-matrix 20% IED), and damage ratio % of the skill.

If multiple skills have the exact same in-built IED, you can combine the skill's damage ratio % and enter it once. Remaining ratio % will be treated as 0% in-built IED.

If the skill has multiple IED sources, use "+" to separate the IED % (e.g. 30+20+20).

To delete a skill, tap on the added skill in blue.
