“Foreseer’s Contract” event has revealed Oracle, an upcoming Dota 2 hero with the ability debuff enemies, heal allies, and turn friends invisible.
“Weave your power into a harmful bolt that stops your enemies and removes helpful auras. Or render an ally resistant to harmful magics. Combine either approach with your double-edged purifying flames, and you’ll have all you need to aid or destroy.
Still in danger? Delay an ally’s doom with a false promise, and give them the time needed to see their destiny to its fullest. As the Oracle, the future is always in your hands.”
