Yeah, but when you make such comparisons in attack, you have to account for
attack penetration and
durability. To a certain extent, they go hand-in-hand. Also, just so that we're on the same page, I was comparing Dimaria to her fellow Spriggans, not fodders.
Anyways, let's go through all of Dimaria's attacks. Her
Age Seal does no damage.
Age Scratch was endured by DF Wendy.
So the only attack that Dimaria literally has left is her laser beams.
In the page you just posted,
Carla was pierced by Dimaria's laser beam. Now as we all know, Carla's
durability is pretty low. That means that less attack penetration (the ability to pierce through the target's defense) and attack power is required for Carla to actually take damage.
On the other hand, let's use TO Chelia (Spriggan level) as an example. Remember this?
The same attack used against Carla was deflected by Chelia with ease. Why? Because Chelia has higher defense. So contrary to the other scenario, it would take more attack penetration and attack power for TO Chelia to be damaged. This feat alone tells me Dimaria's attack isn't that high (considering the fact that really can't do anything against Spriggan-Tier opponents).
