Perhaps it's the redundant words that confused me. Given there is no cooldown to reduce while it's available, why even mention "during the cooldown"? It makes it sound like you're preparing for next time. You should just say "For every 16 gold earned of spent, the cooldown is refreshed by 1 second."

I've not played DotA, so your comparisons are lost on me.
