Io relies on Tether to link with an ally and on Relocate to teleport that pair across the map. Relocate is cancelled if Io is disabled during the cast delay, and enemies see an indicator of the destination, so a stun or hex answers it. Equilibrium raises Health Restoration the closer Io gets to zero health, which healing reduction counters.
Counter items
Scythe of VyseHex disables Io during the Relocate delay, cancelling the teleport.
Abyssal BladeOverwhelm stuns through debuff immunity and cancels a Relocate in progress.
Spirit VesselReduced Health Restoration works against the bonus that Equilibrium grants.
