The damage of Stone Two-Handed Axe is set at Base Weapon + 1, and, unfortunately, there are no upgrades available for this weapon in Zelda: Tears of the Kingdom.

The new Legendary 2-handed axe drops from Fyrakk the Blazing, the final boss of the Amirdrassil raid. It has an item level of 496, over 1000 Strength, nearly 400 Critical Strike and 667 Haste.

In Assassin’s Creed Valhalla, you can dual wield everything — two axes, an axe and a hammer, two shields, and — eventually — two two-handed weapons.
