Now that's really close to what they look like with the heirloom pack iirc
No, the heirloom pack adds accents to weapons. For bows, typically just some cool inlay work. Swords get some golden accents and often stones, in the hilt. Arabian weapons get this but also Arabic inscriptions on the blade. Axes get inscriptions on the head and inlay on the handle, etc etc etc. Basically, it doesn't change much just makes things a bit prettier. Also makes metal look more like metal.
