Unlike Titanite Shards and Large Titanite Shards, Titanite Chunks cannot be purchased, making obtaining them significantly more difficult. They are required to ascend and upgrade weapons from +10 to +14, as well as ascension for standard weapons to Lightning and Crystal weapons, from +0 to +4. Titanite Chunks are also required to upgrade armor from +7 to +9.
- The Very Large Ember must be given to Andre of Astora in order to ascend/upgrade weapons and armor using Titanite Chunks.
