What you are talking about m8?
That is not a scythe. Sounds more like a spear
Of course, you can use some crafting and blacksmithing to improve it. Can add some tenebrium too! Too bad the elemental damage is not perfect
You wanna see what a scythe looks like too?
Edit: you should also remember that everyone and his mom at endgame have high piercing resistance and low/non slashing resistance. 2h is just silly
