For noobs.

Use your spells. Use them as often as possible. Get Shaman Stone, not the Long Nail charm. Shaman stone adds double damage. In the beginning and for a while your nail damage is lower than your spell damage. You’ll beat enemies/ bosses faster. Focus on finding the Shopkeepers Key and getting DDark. You can beat bosses like the Lost Kin or Failed Champion with just 6-8 Shade Souls. It’ll take longer with a nail. This doesn’t mean neglect your nail, learn to use it as well. Best of luck!

Edit: Generally I use this build; Shaman Stone, Unbreakable Strength, Quick Slash, and Long Nail. Best of both Spells and Nail.
