I evolved Q and then used it multiple times on dragon (which is isolated at all times), and about 3 (or more, I only counted three) of the Qs didn't refund cooldown. Then when it got to below 1k HP, my last q refunded CD. It works sometimes, but is not consistent.
1. Evolve Q
2. Go to drag and keep Qing it while you fight it
3. Sometimes it refunds CD, sometimes not.
