DOTA trick ~

- Elune's Arrow, if timed right, flying over neutrals on spawning time, can prevent neutrals from spawning.

- Heroes like Lycanthrope and Dragon Knight who transform can remain in
their transformations even if they cast Mirror Image (Manta Style) by
arranging commands (Hold shift -> move position -> transform
-> manta style)

- Sonic Wave x2, you can actually get hit twice by 1 sonic wave. say
you have a blink skill such as magina, you can be right beside QOP, get
hit by the sonic wave as it comes out and blink in front and get hit
again. this works similarly with x marks the spot.


- When Huskar and Necro's ulti are both boosted by sceptre, it is possible to instant kill anyone.

- Destroy enemies' moutain, just use CM's Frostbite that lasts for 10s with 10s cooldown against it.
(Surprised?!)

- By silencing Rikimaru you make him visible. Rikimaru will stay visible as long as he is silenced.

- FocusFire(Windrunner) can hit invisible enemy if she use it before the enemy goes invisible.

- You can use TP scroll on Undying's Tombstone. You can use Glyph on Undying's Tombestone.

- The knockback effect of Batrider's Flamebreak uses direct positioning.
This means that if you get hit by the knockback just before you Blink,
Teleport or any similar ability, Flamebreak will put you right back
where you were before.
(Yes, it even knock you back to base)

- Decrepify(Oblivion) and GhostForm(GhostScepter) can be used to escape
any Ensnare-based spell, including Ensnare(Naga), Earthbind(Meepo), or
Pit of Malice(PitLord).

- Dirge's Soul Rip can target any building on the game, but with no
effect on them, with the exception of his tombstone, which will be
healed.

- Sand King's Caustic Finale has the same base skill as Ursa's Fury
Swipes. If both Ursa and Sand King are attacking the same target, SK's
attacks will also increase Fury Swipes' bonus damage. When the unit is
killed the explosion damage from Caustic Finale will be dealt to all
targets within 400 AoE so long as the target still has the Fury Swipes
buff at the moment of death.
(Gay partners)

- Armlet can be activated and placed on SpiritBear(LoneDruid's pet)
without it suffering any degen. It will not gain any strength, but it
will gain all the other benefits.

- Waveform Extension, make sure you spam right click move command to
the direction your wave is going. This extends the waveform, most
noticeably when you have a haste rune or just a high movespeed. The
important thing is to spam right click since the waveform trigger moves
morph every .04 secs so the right click move command is canceled every
.04 secs.

- Two separate permanent invisibility will allow the unit to attack and
cast spells without revealing itself. This can be easily reproduced in
DotA using a combination of Mirana's ultimate with either Stealth
Assassin's ultimate or Broodmother's web.
(Yes, imba golden 11 seconds unrevealed even attack and cast spells)

- Zeus's Lightning Bolt will reveal sight over 900 AoE with true sight
over 3 seconds. Don't forget the ministun (0.01 second) on the targeted
unit also!
(Merlini's zeus uses lightning bolt to reveal & destroy wards)

- Although Zeus' Thundergod's Wrath hits all the enemy heroes, and have
true sight, it can't damage isolated invisible enemies (eg. Rikimaru,
Broodmother in web), because that damage is applied before true sight.

- Both the Illusion rune and the Double Damage rune will NOT affect your hero when you're magic immune
(Beware BKB and N'aix users!)

- Radiance is one of the only auras that affects others while you are
invisible as it is based on Building Damage Aura (Tornado); This in
contrast to abilities such as Rot / Pulse Nova where if you go
invisible you will not be able to deal damage to enemies but still
drain your HP/MP.

- When using Mirana's leap there is a 0.001 second windwalk in the
beginning of the animation, therefore it can be used to dodge any
oncomming projectile if the enemy does not have true sight on you.

- Fog of war updates every .4 seconds. So if you Blink into the fog and
use echo slam/Qop scream/heat seeking missle too early, you will miss
due to the fact you haven't seen the enemy yet.

- Some spells based on Fan of Knives (Scream of Pain for example), although doing magic damage, but won't damage ethereal units.
(This includes Pugna's Decrepify and Ghost Scepter's active ability)
