Vamos finishes two trophies: a Fire weapon at +10 and a Chaos weapon at +5. Each starts from its own Normal +5 weapon and needs ten Green Titanite Shards (sold without limit); then the Fire one needs seven Red Titanite Chunks and a Red Titanite Slab, the Chaos one eight more chunks and the second slab. That is fifteen chunks, and the fixed ones found so far (two Asylum Black Knights, two in the Great Hollow, two in Lost Izalith) fall well short. Keep every Red chunk and both Red slabs; both trophies are finished at the Kiln of the First Flame, where a Black Knight that comes back drops a Red chunk each time; the Catacombs (Vamos) bonfire brings you back to him by warp.
