Armlet of Mordiggian toggling can help you survive in situations where you would normally die. Turning it on gives a +25 strength bonus and increases your health. The armlet drains health while in use, so you what you want to do is turn off the armlet with lower HP and then quickly toggle it back on, granting you a health boost. The cooldown period is 2 seconds. An armlet that has been turned off drops your HP for a brief moment, so be sure you aren't taking damage over time and make sure you're not about to sustain an injury from an attack.
Attack Animations
Throughout an attack your Hero normally performs two phases of animation; the first when performing the real attack, and the second is "follow-up" after damages has actually been used. The first animation phase have to constantly finish itself, however you can be able to in fact "cancel" from the second animation phase merely by moving if you are a physical assailant, or by purchasing your Hero to "Stop" if you are making use of a casting capability. When it come to physical attacks, canceling the follow-up animation lets you remain on the step after attacking however for casters it in fact keeps you from making use of the capability, saving you from making use of mana for the capability and having it enter cooldown.
Bottle Refill Trick
You can refill your Bottle without Bottle crowing or going back to your fountain. To do this, immediately give your Bottle to an Ally who has teleported near you from a fountain. This fills your bottle, due to the fountain buff lingering briefly after after the other player has left the fountain. Use a TP scroll, Keeper of the Light Recall, Nature's Prophet Teleportation, or recall on Lone Druid Spirit Bear to help refill an ally's Bottle.
Bottle Spam in Fountain
Bottles refill automatically and instantly in fountains, so spam your Bottle to heal faster. The faster you can heal in a fountain, the faster you can get back out to battle!
Buy Before You Die
Be aware that you lose unreliable gold when you die. If you know death is imminent, access the shop and quickly buy your next item. The item will be waiting in your stash when you respawn!
Cancelling attack animations
Tip 1: During an attack your Hero typically executes two stages of animation; the first when executing the actual attack, and the second is "follow-up" after damage has been applied.
Tip 2: The first animation stage must always complete itself, but you can actually "cancel" out of the second animation stage simply by moving if you are a physical attacker, or by ordering your Hero to "Stop" if you are using a casting ability.
Tip 3: In the case of physical attacks, cancelling the follow-up animation lets you stay on the move after attacking but for casters it actually keeps you from using the ability, saving you from using mana for the ability and having it go into cooldown.
Denying Allied Heroes
This prevents the enemy from gaining any gold or experience from the kill. You are able to deny your allies under two conditions: one, they are under the effect of a poison ability such as Doom's Doom or Queen of Pain's Shadow Spike; two, your ally is under a certain percentage of health. A-Click to deny an ally. Allies will still lose unreliable gold upon death.
Drop Attribute Items to Get Restorative Bonuses
When you're looking to restore health or mana, drop items that grant attribute boosts. Then use your restore. Doing so will give you a higher amount of health/mana in your pool, once the items are back in your inventory. From the percentage-based health/mana gauges, you receive a very helpful bonus. Items can be picked up or destroyed by other heroes, though, so do be mindful of your surroundings before you drop.
Force Staff item
The Force Staff item has more uses than many people see. When an ally is stuck in place (Winter Wyvern's recover and an enemy Crystal Maiden's Frostbite enter your mind, in addition to any kind of stun), you can use this to move them far from the enemies (provided they were dealing with towards you prior to being stunned/healed).
Losing Tower Aggro
Towers have attack priority that decides what they hit. If you are dying and want a tower to stop attacking you, A-click an allied unit. The Tower should change targets as long as other units are within range.
