How about a new tileset. Big tree, that functions as a "wall" tile. More of these in place of the regular trees would fix the mob issues too, as you'll have at least your back covered.
EDIT: So I notice there are more flaming/lightning weapons, but there's no difference between them and the original. As I recall from my weapons comparisons, enchanted weapons are heavier than their normal counterparts, presumably to compensate for the added damage.
EDIT: So I looked it up, it's not the case with the flaming sword, but that is the case with the thunder hammer.
EDIT: So I notice damascus steel comes after adamantine, which in my opinion is rather silly. It should be before/after meteoric steel if you ask me.
