Here is the weapon.
Stats I think I will make it a bit more balanced and an energy weapon.
It will be heavier, but more drainage and damage than Bright Roar.
Its basically an energy Seraph Blade, but a bit different. Maybe higher damage.
450 - 490 damage
Energy Drainage is around 120.
Energy usage is 90
Heat Usage is 90.
Weight is 72
You can change it around since I am not good at making stats.
(This is probably a physical nightmare.)
(Or just a bad weapon.)
(Or maybe an op weapon.)
