Different kinds of hardening abilities Ok, as far as I know, there are 3 types of hardening.

White hardening = Jaw and Warhammer
Blue/Crystal hardening = Female, Attack and Beast
Natural hardening = Armored

My question now is, are those abilities combinable if those are different kinds of hardening?
Like could the armored, jaw, or the Warhammer also be able to have additional crystal hardening?
There is no such thing called &quot;white&quot; hardening, Warhammer hardening is crystal type, like female or attack titan, and Jaw hardening is neither natural nor white(crystal), but it looks like the natural type. so because armored titan is the only titan that can do natural hardening, there won't be any hardening combination.
EDIT :
I was wrong about Warhammer's body, it IS hardening but I don't think it's different from other types of hardening
