Defense, or DEF for short, represents how much Physical damage that a unit can withstand. See Damage/Physical for more information.

Enemies' DEF values are not numerically shown, unlike those of Operators and summons, instead displayed as one of the following ten ratings which roughly indicates their amount:

SS	>5000
S+	3000 ~ 5000
S	2000 ~ 3000
A+	1200 ~ 2000
A	1000 ~ 1200
B+	800 ~ 1000
B	500 ~ 800
C	200 ~ 500
D	100 ~ 300
E	<100

Modifiers

Buffs

Many Operators have the ability to increase the DEF of friendly units (including themselves), but those will not be listed on this page due to their numbers. This also applies to enemies with the ability to increase the DEF of other enemies and themselves.

One of the most notable examples is the DEF Up skill, which increases the user's DEF for its duration.

Debuffs

Friendly units on an Eroded Path/Corrosive Ground tile have their DEF reduced by 50%.
