Smash!: Achievement STEAM of Assassin's Creed Origins

There are lots of breakables (vases etc.) inside tombs. You'll have to explore all tombs for the trophy 'Old Habits'. Smash vases with melee attacks for this. Just remember to always hit the vases inside the tombs.
There are also breakable oil jars in most enemy camps. In all likelihood this trophy will come naturally over the course of your playthrough.
