History of Speed Booster

Speed Booster is a secondary Arc buff, added in Season 18: sprint for 2.5 seconds while Amplified. It gives about 12.5% faster sprint, 50% more slide distance, 15% PvE damage resistance and higher jumps, lasting 2 seconds after you stop sprinting. In The Edge of Fate, the AION Renewal set grants it via the 2-piece Force Converter and instantly via 4-piece Reactive Booster.
