if this is a thing, than it must be fixed as fast as possible
Technically it's still a 26 defense if you don't include the shield... but it's still powerful because you can cast only 2 lightning and hide behind a shield because each lightning hits 4 times with 40 damage (40 Dmg x2 lightning x4 hits = 320 magic dmg) and you stand behind the shield and only take 1 damage. Moreover - shields in the game are broken because if you raise a shield you will get x10 DEF stat which means if you have only 10 DEF stat of character it's 10x10 = 100 DEF.
I'm already personally tired of goblins running around with a wooden shield because they're pretty hard to penetrate sometimes even with a halberd at the start because they have too much DEF stat even without blocking and 100 HP. I mean - you can kill them of course especially in an open field but it's a lot of running.
In general about the "shields are broken"... I don't mean the Lona character (because you can't just nakedly grab a shield and save yourself from all the damage even without blocking) I am talk about all monsters or humans with shield (But this shields problem is pretty broad... so there's no point in talking about it so much at now).
