moonlight butterfly horn is very easy to get, just before ornstein. you get it the soul from the moonlight butterfly in the darkroot gardens. despite being a boss revolving around magic attacks, shes very easy to beat with magic of your own. crafting the weapon itself is probably one of the easiest. grab the lightning spear in sens, go to the giant blacksmith, downgrade it, ascend it, and boom, new weapon.
velkas rapier can be obtained before anor londo too, by venturing into the painted world, along with some very cool armour sets.
moonlight greatsword is the most popular. if you do coop a lot, the special attack is very flashy and people like to spam it. can be obtained by a tail cutoff from the dukes archive boss. dukes archive is the popular spot for blues, so if you're aiming for enchanted+5, might as well just kill the area's boss rather than farm that area for chunks.
The problem is those are still a bit too late for my tastes. Why bother struggling in the early game with magic when you can jump into a melee build ASAP.
