Turtle shell reduces physical damage taken from all sides but the front by 20%, when it's supposed to only do that for the back and half that for the sides and front.




Also as a side note, when you get hit by an attack with the turtle shell equipped, it shows the Reduction message each hit.

I've had it reduce physical damage from the sides whenever they were within 1 range. It probably works the same way that Cobra does now, and gives the defense bonus of 20% to anything past 1 range in the side tiles, but the melee is 10%.

This is probably ™ working correctly.

It uses line of sight I believe, yes.
