The spells all suck IIRC. The crystal rapier looked interesting but I never upgraded it or tried it. The ice sword you get from the mini boss down the life in boreal is it? relatively early is pretty tits. The only probelm with it is it takes twinkling to upgrade but its pretty nice.Are any of the boss souls items worth it?
Most of the weapons were pretty hefty which makes them slow and in an aggressive game that can make things difficult or less than optimal.
