^ Dude that's Relic of Fortune, not Haste.
Relic of Fortune gives haste (which increases movement and attack speed) for 18 seconds after opening a chest. It also gives +10ER on a cheststreak for 20 seconds.
Relic of Haste increases movement and attack speed by 35% after using magic for 15 seconds. Or at least it's supposed to. Since the Labyrinth Update, it's been giving the speed buff for 15 seconds at the beginning of the match, after which it does nothing as far as I can tell.
The gods overestimate themselves.
