Matchup phases

We split the game into three stages. Each has a concrete action plan.

LaneThe lane suffers from harass. Keep your distance, pull creeps under tower, ask the support to draw aggro.
Mid-gameIn 5v5 fights the enemy catches us first. Without BKB any cast = death. Keep Linken's or a save position.
LateThe opponent reliably delivers control from the back line. Grab save items.

The main task is to convert the early lead into tempo. Every small advantage accumulates by minute 15 into a tangible GPM gap.

FAQ

Where does the -6.7% gap come from?

The OpenDota live feed — the public Dota 2 statistics API. The gap is calculated over millions of ranked games at high MMR. At low ranks the effect is weaker.

Can you win this matchup?

Yes. -6.7% is statistics over a sample, not a verdict. With BKB / Linken's we play out in 40–45% of cases.

Will Umbrella help?

The Umbrella subscription gives you Dodger, Item Auto-Use and Info Screen. On hard matchups the difference is ~2–3% win rate in favor of the Umbrella user.

Where do I get auto-combo on Mars?

On the guide page — the "Umbrella scripts" section. A ready config with binds is in CFG.
