I have finally gotten around to play my proposed challenge where magic completely replaces weapons.

Here's a breakdown of the limitations I set for this run:
* I can't use weapons or drink estus flask. I decided to ban the latter only after 2 hours of the run.
* I can't level up any stats except Attunement, Intelligence, and Faith. I can't wear items that increase my HP.
* I can't wear equipment that increases my poise.

This way I plan to beat all the bosses in the game, hopefully even in the DLC (but that one will be tough...). I also want to replicate another challenge I did years ago - to complete the catacombs using Force as my only offensive spell.

So far I've completed the easiest part of the game - the bells. I don't expect much trouble before the Great Soul hunt though.

Some thoughts on what I already experienced:
Magic is more than enough to go through the early stages of the game, I basically never had to think about my spell uses, and I tend to kill every enemy on my way. No need for Dusk's ring either, fortunately.
With that said, I HATE how much soul arrows miss! It's enough for an enemy to move a little and that damn "homing" projectile flies pass them. I rely on Combustion much more than I expected to lol.
