Virtuous Grief are Combat Bracers in NieR: Automata.
"Stark white samurai gauntlets, kept pristine. Their master never saw a moment of conflict."
Weapon can be found in the Forest Zone. Teleport to Forest Zone: Center, and navigate to the river that runs through a small wooden bridge. Then, follow the river down to the cliff and scale up the rocks to get on top of the light gray area shown on the map. Once you are on top, keep moving until you see a dead android next to a gap of the rocks. Jump across the gap and you should see a hollowed tree with chains on it. The weapon should be inside said tree.
- Level 1
- I see you in my sleep. Restless sleep. My heart flies to pieces each time I wake. I burn to see you in the real world.
- Level 2
- I hunt for the woman who pines for you. The scream pleases me. Your body and heart shall be mine.
- Level 3
- Your heart. I long for it. Yet it does not return my love in kind. All you care for is your cold, dead wife. So I must at least take your body.
- Level 4
- Your head is mine. Beautiful head. The eyes that scorned me are so lovely now. Hate me if you like. Begrudge me all. You are still mine forever.
