Which has a higher dps - Lightning Blade or Darkmoon Blade?

With 60 faith, which does more damage on average, Lightning Blade or Darkmoon blade?

Solution 1:

Neither of these will do more damage "on average" as they are both weapon enchantment miracles that raise your weapon by 50 damage in their respective elements and not actual weapons.

If you wondering which will be more effective to more enemies, it will likely be Lightning Blade, as that seems to be a more common weakness, but bear in mind that if this spreadsheet of boss elemental weaknesses is anything to go by, most enemies will only be taking 1-5 more damage from Lightning than Magic anyways.

Since these are both just miracles, it would be best to know your specific enemy's weakness and then enchant your weapon accordingly.
