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.
