Inspired by the stronghold god, selFu, I made a build around my perfect 5th Ergo Sum that can perform in high end content. in a raid/dungeon scenario that calls for swords, after swapping to 3x surges and 3x lucent blade armor pieces it becomes the highest DPS sword in the entire game.
Been using strongholds & Lament since beyond light but after the completely unwarranted nerf to my favorite exotic, I've sadly decided to retire it (Please Bungie revert the nerfs and my life is yours).
Since I forgot to go over my weapons, here are the rolls:
New Purpose: Feeding frenzy and Desperado (used for diamond lances and anti-champs mainly)
Ergo Sum: Caster Frame, Jagged Edge, Perfect 5th.
Pro Memorial: Fluted Barrel, Extended Mag, Reconstruction, Bait and Switch
