Granny deceived me

I bough a sword from the item shop it’s said it would add +19 attack, actually it took me-2 down

Everyone knows that swords lose half their value the minute you drive them off the lot.

Had this sword only attack or also a secondary skill bonus like more ice damage, blunt damage and so on ? If that sword had +19 attack as you said, but the secondary attack bonus was less than your old sword is normal that you lose “attack”

P.S.: Buy a sword for only +19 attack it’s a poor investment
