Lich Bane
At the start of Season 2021, we revamped Lich Bane to broaden its user base by removing its ability haste and increasing Spellblade's damage and cooldown. These changes made it very powerful as a burst tool, but that burst also got a few nerfs throughout the year. As a result, Lich Bane was left feeling pretty underwhelming for its core users, so we're partially restoring it to a healthier state.

Rylai's Crystal Scepter
Rylai's has been struggling to find its place in the last couple of seasons because it's been trying to serve tanky battlemages, burn mages, and AP supports alike all at once. We're focusing on its purpose as a utility item by lowering its cost and increasing its health to make it more accessible to tankier midrange mages and supports.

Turbo Chemtank
Turbo Chemtank's update during Preseason 2022 was designed to let tanky gankers and initiators store movement into one big turbo blast for those moments when they gotta go fast. However, Refuel was stacking too well with dashes, which meant it was being used as a DPS source for non-tanks. While we admire the creativity here, Turbo Chemtank is supposed to be for, well, tanks, so we're adding some limits to the way its passive stacks. Ultimately, these adjustments shouldn't affect its intended use cases very much. (These changes also apply to its Ornn Masterwork item, Turbocharged Hexperiment.)
