Why does there seem to be so little love for magic weapons that AREN’T swords? 13 magic items that are sword only, most of which could easily be other weapons per RAW. No Flametongue Greataxe or Vorpal Glaive option beyond DM fiat?Simplicity really, so you can roll on table and get an item. No balance behind it – swap weapon types as you wish.
