Orianna vs Riven Counter Pick

Riven pays no resource whatsoever — her abilities cost cooldowns and nothing else, while Orianna spends mana on every command. In a long exchange that favours Riven; across the 137 games recorded on patch 16.13.1 it did not, and Orianna finishes at 54.0% with an Easy rating. The explanation is the 525 against 125 attack range gap and what Riven has to spend to cross it.

• Broken Wings is her approach and her exit. Three activations with a knockback on the last one — using them to arrive leaves nothing for the retreat.
• Valor blocks damage once. A short step forward with damage blocked answers a single Command: Attack, not the Ball already sitting behind her.
• Blade of the Exile extends her reach. Wind Slash gives Riven a ranged finisher, and that is the moment the shield from Command: Protect earns its cost.

Orianna’s frailty is real: 565 base health, 20 armor, 26 magic resist and 44 base attack damage that contributes nothing in a straight fight, against 630 health, 33 armor and 64 attack damage. Riven’s damage is physical and her difficulty rating is 8 against Orianna’s 7, so everything hinges on whether the engage lands cleanly. Keeping the Ball between herself and Riven turns one mistimed Ki Burst into a full Command: Shockwave.
