I was going to covert the Great Scythe into either Lightning or Fire so that I wouldn't have to spend all my points in DEX. Not smart?
I don't want to build INT so I was hoping to use the lightning spears as my go-to ranged attack. Bows just don't do it for me.
Elemental damage in this game is weird since it ends up being less than what you'd get on paper since the damage is split, and has to be calculated across two defense values from enemies. I mean, if you wanna go that route it's not going to ruin your game or anything but you'll get less damage than what you'd get from a Dex build.
The problem with Lighting spear is that a) it has shit damage, b) its casting time is obscenely long and c) you have to lock on to an enemy to hit it. I did a faith run and Great Lighting Spear was pretty useless after Sen's. Overall I found faith somewhat lackluster. Heal becomes useless after you get the Rite of Kindling. The Lightning Spears also have low damage. Wrath of the Gods is awesome and so are Darkmoon and Sunlight Blade, but you get those kinda late. At least I didn't have to worry about Homeward Bones.
Might as well get a bow since you'll be putting points into Dex anyway. It's much better than the Spears and can easily be free aimed.
