Expert Tips

Counter Strike (E) dodges all auto attacks during the animation and stuns when activated. Pop it during enemy AA-based trades.
Endure (E) the auto attacks, THEN activate stun. A common mistake is activating too early.
Relentless Assault (passive) stacks are your DPS — always extend fights once passive is fully stacked.
