The Soft Support's job this phase

Stand between the enemy carry and the creeps — make them choose between XP and HP.
Secure the minute-6 power rune for your mid — that's your first rotation.
Place Observers on rune spots or enemy rotation paths, not random cliffs.

Why this way? How OpenAI Five learned

One hero, one role first
OpenAI's first bot played only Shadow Fiend, only mid, until it mastered it. Stay on Disruptor 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.
