Don't be a scrublord and complain about fatrolls you have batshit retarded damage and strong armor
Use magic sparingly, it's nature in this build will be limited to killing enemies that WILL out-run you and to make your enemies hesitant in their attacks.
That being said Crystal +4/5 cmw then switch to the +15 after it's out, this is to keep your weapon from breaking like hopes and dreams in the trash compactor of life
This is not a build for the easy going as it like the lottery trying to hit with a greatsword and has a GLARING weakness to magic
