Smoke of Deceit is a pivotal item in Dota 2 that, when used effectively, can turn the tide of a game through successful ganks or by securing key objectives like Roshan. Here’s an in-depth guide to mastering smoke ganking.

Basics of Smoke of Deceit

• What It Does:  Dota 2 Smoke of Deceit makes you and nearby allied heroes invisible to enemy wards and creeps, allowing you to bypass common vision spots undetected. However, getting too close to enemy heroes or towers will dispel the smoke.
• When to Use: Ideal scenarios include setting up ganks, sneaking into Roshan, or repositioning for a surprise team fight initiation. It’s particularly useful for breaking stalemates where neither team can safely engage.

Planning a Smoke Gank

• Team Coordination: Communicate with your team about the intended target or objective. Ensure key heroes with initiation or lockdown abilities are included in the smoke.
• Timing: Consider enemy heroes’ positions and the state of lanes. A pushed-out lane may indicate the enemy is jungling or could lure them into a false sense of security.
• Vision Control: Before smoking, ensure there are no enemy wards around that might spot your team grouping up for the smoke. Sentry Wards or a Gem of True Sight can help secure your starting position.

Executing a Smoke Gank

• Pathing: Choose a route that avoids common ward spots and maximizes the chance of catching the enemy off-guard. Use the minimap and any existing vision to predict enemy movements.
• Target Priority: Identify key targets—typically high-impact supports or core heroes—and focus on taking them out quickly in the ensuing fight.
• Dispelling Smoke: Remember that smoke dispels when near enemy heroes, even if they are not visible. Use this to detect nearby enemies in fog of war or hidden spots.

Advanced Smoke Gank Tactics

• Baiting: Use an allied hero as bait while the rest of the team, under smoke, waits nearby to counter-initiate.
• Objective after Gank: Always have a follow-up objective in mind after a successful gank. This could be taking a tower, securing Roshan, or placing deep wards in enemy territory.
• Sneaking Roshan: Smoke can be an effective way to sneak a Roshan kill, especially if the enemy has map control. Leave one hero outside the pit to break any incoming smokes or to scout for enemy movements.

Common Mistakes to Avoid

• Wasting Smoke: Avoid using Smoke of Deceit without a clear objective or plan, as wasted smokes can limit your strategic options later on.
• Grouping Up Too Early: Grouping up before purchasing Smoke or while in vision of enemy wards can give away your plan. Ensure you’re in a safe spot before using it.
• Neglecting to Push Lanes: Lanes pushed toward your side of the map can indicate to the enemy that a smoke gank is underway. Push out lanes to maintain map pressure and ambiguity.

Item and Hero Considerations

• Quick Initiation: Heroes with blink or long-range initiation abilities (e.g., Axe, Earthshaker) can quickly capitalize on the element of surprise provided by smoke.
• Tracking Cooldowns: Be mindful of the cooldowns of key abilities and items (like BKB or ultimates) on both your team and the enemy’s. Engaging without these can lead to a failed gank.

Mastering smoke ganking requires practice, coordination, and strategic foresight. When executed correctly, it can provide your team with crucial pick-offs, swing the momentum of the game in your favor, and secure vital objectives.
