The Midlaner's job this phase

Focus on last hits & denies — a 10-creep lead by minute 5 is a real level advantage.
Minutes 6, 8, 10, …: check water/power runes. A full Bottle means you can spam spells.
Ask a support to arrive 30 seconds before power runes when your lane is rough.

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 Bounty Hunter 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.
