What Is “3rd Map – 1st Aegis” in Dota 2 Betting?
In Dota 2, the Aegis of the Immortal is dropped by Roshan and allows the hero carrying it to respawn once after death. Because Roshan fights often decide the momentum of a match, bookmakers offer markets based on which team takes Roshan first.
Meaning of the Market
- 3rd Map → The bet only applies to Game 3 of a series
- 1st Aegis → The team that kills Roshan first and picks up the Aegis
You are betting on which team will secure the first Aegis in Map 3, regardless of who wins the map or the series.
When Is This Market Available?
This betting option is usually available when:
- The series format is BO3 or BO5
- The match is tied 1–1, forcing a deciding 3rd map
- Offered both pre-match and live betting
Betting Options Available
Typically, bookmakers provide two main selections:
- Team A – 1st Aegis (Map 3)
- Team B – 1st Aegis (Map 3)
Some platforms may also offer:
- No Aegis (rare, only if Roshan is never killed)
How the Bet Is Won or Lost
| Situation | Result |
|---|---|
| Your selected team kills Roshan first and picks the Aegis | Win |
| Opponent gets the first Aegis | Lose |
| Match ends before Roshan is killed | Usually void (depends on bookmaker rules) |
Important:
Only the first Aegis in Map 3 counts. Any later Aegis pickups do not affect the bet.

Why Bettors Like the 3rd Map – 1st Aegis Market
- High odds compared to match winner
- Focuses on early–mid game strategy
- Great for live betting
- Less affected by late-game comebacks
This market is ideal for bettors who understand team drafting, Roshan control, and map awareness.
Key Factors to Analyze Before Betting
1. Draft & Roshan Lineup
Teams with heroes like:
- Ursa
- Templar Assassin
- Troll Warlord
- Shadow Fiend (Desolator build)
These heroes kill Roshan faster, increasing first Aegis chances.
2. Vision Control & Map Pressure
- Strong warding around Roshan pit
- Supports with vision skills (Beastmaster, Clockwerk, Treant Protector)
Teams that dominate vision usually control Roshan fights.
3. Team Playstyle
- Aggressive teams often force early Roshan
- Defensive teams delay Roshan until late game
Check historical stats on average Roshan timing.
4. Side Advantage (Radiant vs Dire)
- Radiant traditionally has a slight Roshan access advantage
- Consider which team starts on Radiant in Map 3
