Spells like Rift Walk get small counters that you will see above your champions toolbar. When you use the spell again, another counter will be added and the duration of the ability will be refreshed while you wait for the abilitys' cooldown. Riftwalk doesn't increase attack damage, the stacks increase magic damage caused to opponents standing in its area of effect.
You can get a total of 9% cooldowns from masteries, and about an additional 20% with nothing but cooldown runes (anyone know for sure?). The rest of your cooldowns will come from items, if that's what you choose to build. Be careful though, because there's a 40% cap on cooldowns for all champions.
