When it comes to infusing weapons with lightning damage in Dark Souls 3, players have a wide range of options to choose from. However, not all weapons are created equal, and some are simply better suited for this type of infusion than others.
The best weapon for lightning infusion in Dark Souls 3 is one that has high base damage and scaling, and that can be buffed with lightning-based spells or resins. Some of the best choices include the Lothric Knight Sword, the Claymore, and the Dragonslayer Axe. These weapons all have excellent damage output, and they can be further enhanced with the use of lightning buffs.
