Nature's Prophet
The items that shut Nature's Prophet down, 3 heroes that trouble it, and your answer when you play it.
Members onlyOne hero, one role first
OpenAI's first bot played only Shadow Fiend, only mid, until it mastered it. Stay on Nature's Prophet in one role before moving on.
Small, measurable rewards
OpenAI Five was rewarded for last hits and staying alive long before it understood winning. That's why each journey stage has one number to hit.
From yourself to the team
Its 'team spirit' rose over the game: early on, look after yourself; late, play for the team. Each phase's meter shows the split.
Use proven builds
OpenAI Five's builds were hand-written, not trial and error. Start from the pro build, then experiment.
