Silver long sword doing 4 damage. Bound dagger doing 4. Iron long sword 2 or 3. Is this normal? Strength is about 45 and blade skill at 26. No diseases or anything out of the ordinary. Can't kill anything with these swords and blade skill is taking forever to level. Level 5 now and only gained one skill point in blade. This is a spellsword character btw with combat specialization and blade minor skill.

Those sound like pretty average vanilla stats, yeah.

If Blade were a specialized major you'd see a greater skill increase and starting damage due to the specialization bonus. But weapons skills take a while to level and doubly so when they're just minors.

Are you using any mods?
