The uchi is too good not to use early on. Good reach, speed, damage, and bleed. It just sucks for poise breaking. I think it's the best weapon you can find in Limgrave, hands down, for any build. Just add ashes/affinity to taste.
No, it's only a little inferior to heavy weapons if you use the L2-R2 to stagger break.
Just tried another magic weapon, they never seem to disappoint, this time : dark moon greatsword, this game incarnation of the moonlight sword. After using the weapon art to buff it, R2 launches projectiles that cost
no fp and can one or two shot common enemies in one of the worst area of the game, the haligtree city. It also pushes people away slightly and works on the heavier dudes that take 5 hits to kill.
Did I also mention, it staggers break the tree defenders in a few hits of R2 too?
It's not just the moon katana boyz, all INT weapons seem pretty good. I also recommend Wing of Astel.
