One of the things I like about Demon's Souls that I wish Dark Souls had kept was the diversity of weapon paths.
In Dark Souls, the paths are normal, stronger normal with awful durability and no fixing it (Crystal), fixed damage (Lightning, Fire, Chaos), Faith scaling (Divine, Occult), Magic scaling (Magic, Enchanted), and just shit (Raw).
In Demon's Souls, they were normal, Dex scaling (Sharp, Spider), Strength scaling (Crushing), balanced scaling (Quality), magic defense (Cloud), bleed (Tearing), faith and healing (Blessed), magic (Crescent, moon), and poison (Mercury). You feel like you have more choice.
(Also, Demon's Souls needs a Scimitar weapon that works for the Blessed path.
What's the point of having a bunch of slight variations on the same weapon with the Scimitar, Kilij, and Falchion if they all upgrade on the same paths?)
After completing 4-1 on a new save file yesterday, FUCK manta rays. I died twice because I locked onto the wrong target.
