Roshan, the Immortal, occupies a pivotal role in Dota 2 matches, granting significant advantages to the team that defeats him. Securing Roshan can provide the Aegis of the Immortal, Cheese, and later, Refresher Shard and Aghanim’s Blessing, which can turn the tide of battles and pushes. Here’s a strategic guide to Roshan in Dota 2.

Timing and Preparation

• Early Game Awareness: Roshan can be contested as early as the mid-game with the right hero compositions. Heroes like Ursa, Troll Warlord, or Templar Assassin can take Roshan relatively early with minimal items.
• Itemization: Items like Medallion of Courage or Solar Crest can significantly speed up the Roshan kill. Lifesteal items or abilities also help sustain during the fight.
• Warding: Secure vision around the Roshan pit with Observer and Sentry Wards. Ensure you have Sentry Wards inside and around the pit to deward and control vision.

Team Composition and Abilities

• Minus Armor: Heroes or items that reduce armor (Slardar, Desolator) can drastically decrease Roshan’s effective health, making him easier to kill.
• Sustain: Heroes with healing abilities or items ensure your team stays healthy during and after the Roshan fight, ready to engage in case of a contest.
• Aoe Control: Area of effect (AoE) control spells can be crucial if the enemy team attempts to contest Roshan. Heroes like Enigma, Magnus, or Tidehunter can secure the area and turn team fights around.

Contesting Roshan

• Smoke of Deceit: Use Smoke of Deceit to approach the Roshan pit undetected, either to take Roshan by surprise or to prepare for a contest.
• Split Pushing: Applying pressure on other parts of the map can force the enemy team to respond, creating a safer Roshan opportunity. Teleport Scrolls and Boots of Travel are essential for quickly joining your team at Roshan if needed.
• Snatch and Steal: Heroes with abilities to jump into the pit (Storm Spirit, Puck) or snatch the Aegis (any hero with a quick blink or grab ability) can turn an enemy Roshan kill into an advantage for your team.

Post-Roshan Strategy

• Aegis and Cheese Management: Generally, the Aegis should go to your team’s carry or a hero likely to be focused in fights, while Cheese is best on heroes with high health pools or mana costs.
• Objective Focus: With the Aegis advantage, prioritize taking objectives such as towers, barracks, or even forcing team fights, knowing you have an extra life.
• Cooldown Awareness: Be mindful of the Aegis’ 5-minute duration. Plan your pushes and engagements to make the most out of the Aegis before it expires.

Advanced Roshan Strategies

• Baiting: Sometimes, starting Roshan can be a strategy to bait the enemy team into a disadvantageous fight, especially if you have superior vision or area control.
• Force Buybacks: After securing Roshan, pushing high ground can force the enemy team to use buybacks, which can be advantageous even if you retreat without securing a rax, as it economically weakens the opposing team.

Mistakes to Avoid

• Lack of Vision: Attempting Roshan without adequate vision is risky and can lead to devastating counter-initiations by the enemy team.
• Neglecting Lane Equilibrium: Ensure lanes are pushed out before starting Roshan to avoid giving away your position and intentions.

Mastering the art of Roshan in Dota 2 requires not just brute force but strategic foresight, timing, and team coordination. Successful Roshan kills can provide your team with significant advantages, from gold and experience to the crucial benefits of Aegis and Cheese, helping to cement your path to victory.
