Question: dark souls 3 how to upgrade weapons?
Answer: The first 3 upgrades will require Titanite Shards, then from +4 to +6 you'll need Large Titanite Shards. From +7 to +9, you will need Titanite Chunks. Finally, to push the weapon to its maximum potential of +10, you'll need a Titanite Slab. Once a weapon is upgraded to +10, it cannot be further upgraded.
