Last hitting is a critical part of Dota 2 especially in the early laning phases. It allows you to gain crucial gold that will lead to you being able to purchase better items for your hero.
Items that can either make you a wrecking ball carry for your team, a life saving support, or a “look out here he comes” initiator.
The other side of last hitting for gold and experience is denying. Denying is taking a last hit away from the enemy on your own creep, tower or teammate.
This is done by landing the hit that kills them. This can not be done by right clicking on the creep, hero or tower. Well not without a script anyway.
How to Deny
To attack a friendly unit, hit the force attack keybind which is defaulted to “A” then click on the unit that you would like to deny.
Units that can be denied
there is a requirement if you are trying to deny a friendly unit.
To deny a creep, that creep must be below 50% health.
To deny a tower, the tower must be below 10% health.
To deny deny hero, the hero must be below 25% health AND have a damage over time debuff that’s ticking away at their health.
If you try to without these requirements nothing will happen when you use the force attack keybind.
Whats the purpose of Denying
This depends on what unit you are denying.
If you are denying a creep the enemy will receive no gold and will only receive 36 experience which otherwise they would have received 62 experience for a melee creep and 41 experience for a range creep.
This is primarily used during the laning phase to lower the rate of experience enemy heroes receive giving your hero a lead in experience.
With an experience lead you will receive high ranks of your hero abilities and your ultimate before the enemy, which can lead to better farming and/or hero kills.
Unlike denying creeps, a denied tower will still give gold to the enemy heroes, but at a lower gold amount.
Here is the standard gold vs denied gold for towers
Tier 1 – 264 gold vs 100 gold
Tier 2 – 312 gold vs 120 gold
Tier 3 – 358 gold vs 140 gold
Tier 4 – 405 gold vs 160 gold
This is particular strong because for one you are denying gold from an entire team and there is a set amount of towers in a match.
Unlike creeps in which if you get denied one creep, there will be others that you can get gold from but If a tower gets denied then you are out of luck for that tower.
When heroes are denied, the enemies will receive no gold or experience but the hero that died will still lose gold.
A secondary effect is that you will seem like a pro player, receive applause from your team and angry chat messages from the opposing team for denying them gold from an otherwise guaranteed kill.
So whenever possible try to get the deny, especially in the laning phase this will help you to gain a experience and gold advantage, giving your hero a lead on the enemy heroes in your lane.
