Probably the worst design in the game. It is required that you have a character with a large shield. Because you had decided that it should be given a modal ability that reduces incoming ranged damaged by 50%.
50%. Not 20, not 30 but a flat 50% reduction. What?
And on another note anyone using a large shield can be expected to hit one in three hundred attacks in POTD. Anyone equipped with a large shield and heavy armor just takes up a slot in the party that just... sits there really. It's not fun at all. If you take this into account it doesn't really feel like you have 5 full party members. You have that thing that sits there and then you have 4 more characters.
It further punishes the fact that the party cap is stuck at 5. I can't help but feel any party I make just feels... barely short of being complete.
