The community consensus for the best weapon in Iron Soul: Dungeon is the light sword.

Why the light sword wins

  • Light weapons have fast attack speed, which means higher damage per second overall.
  • The light sword specifically balances speed and damage better than other options.

What to avoid

  • Heavy swords — they hit hard but swing too slowly, lowering your overall DPS.
  • Crimson — avoid using the Crimson weapon in the Endless Tower; it performs poorly there.

The takeaway

If you're unsure what to craft, go with a light sword. It's the safest, strongest all-round choice. For the full ranking across weapon types, see the weapon tier list.
