Eif or Eir does no damage by themselves
Gungnir is a mage weapon so it deals very little melee damage
Mjolnir would technically deal the most damage out of all of these because itās a warrior weapon and deals more melee damage.
You need to add Geyser or Flame Shuriken to the mix to even like ādeal damageā
Also the fact the Gungnir and Mjolnir varies on pots.
