Patch 4 added some new weapons:
- Phalar Aluve, a Longsword+1, close to the Underdark-Fort
- 4 Githyanki weapons from Githyanki's Patrol, next to the Mountain Pass
- Some new weapons from Wood Woad, Shadow Druids or Kagha, a new magic Staff I think
- A new drop from the Bullete in the Underdark that I don't remember
I'd like to give more details or add these weapons to the wiki, but my savedata file get corrupted and I can't continue or load my playthough.
