TFT Patch 12.12b is considerably bigger than a normal b-patch with three weeks between the release of Patch 12.13 instead of the usual two. These changes are toning down champions that were just too strong as a result of the patch, as well as giving much-needed buffs to weaker champions.

Below, we've listed out the full patch notes for TFT Patch 12.12b.
