How this matchup plays

Getting caught by a Frostbite is especially dangerous for Io. While the root doesn't stop Io from casting its spells, it does prevent the forced movement from Tether, meaning it can't pull itself to a fleeing ally to escape. This isolation often leads to a quick death. In teamfights, Crystal Maiden's whole plan punishes Io's positioning. Io needs to stay close to a partner to be effective, which clumps them together perfectly for a Crystal Nova slow followed by a full Freezing Field. This forces Io into an awkward spot, unable to fully commit to its partner without putting both of them at risk from Crystal Maiden's area damage.
