Hero Mastery
A forest warden: Enchant recruits creeps + slows, Nature's Attendants heals an area, Untouchable slows attackers, and Impetus deals distance-based damage.
Your GPM, last hits and damage per game against other Enchantress players — average vs Top 20%.
Members only5 stages, each with one target from your own games and one short quiz. Make Enchantress your mastery hero to start — progress shows on Home and Arcana.
Sign in through SteamSkills in lane — Max Enchant (W) for the slow + a strong creep; max Nature's Attendants (E) for a big area heal. Untouchable (R) slows the attack speed of anyone hitting you.
Untouchable — anti-carry — Untouchable drastically slows attackers' attack speed — you shut down an enemy carry just by standing near them.

Enchantress
The items that shut Enchantress 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 Enchantress 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.
