Riki

Riki, or Rikimaru, the Stealth Assassin is a melee agility Hero that uses stealth in order to surprise enemies and quickly kill them. His trademark ability, Permanent Invisibility, allows him to sneak into the shadows to hide and slip by without giving himself away.

Though Riki might be a great hero for beginners to use, he encourages them bad behavior and metagame especially if they have just started out playing. Riki has some item dependency and still requires smart thinking and map knowledge to escape due to his low health. He is recommended for intermediate players.

Gameplay
Riki's invisibility is both his greatest strength and his greatest weakness. On one hand, it makes him able to surprise enemies and farm with very little concern. On the other hand, without invisibility he has no real defense. His early game priority is reaching level 6 quickly. Once he has permanent invisibility, he still has to watch out for revealing items such as Dust of Appearance and Gem of Truesight, as well as abilities that Silence him and prevent him from going invisible. If he stays alive and picks off lone enemies, he can quickly get out of control.

Smoke Screen provides a powerful Silence and gives enemies a high miss chance, as well as slowing them down. If targeted properly, it can hold an enemy down long enough to finish them off. However, enemies must stay in the area to be affected. A good strategy is to throw a Smoke Screen in the enemy's path, rather than where they are presently. Blink Strike is Riki's chase and escape ability. It operates like other Blink abilities, in that it allows Riki to teleport to a target quickly. However, Blink Strike must target a unit. It helps catch up with fleeing enemies, jump into fights quickly, and escape from situations by targeting allies. Blink Strike pairs well with Backstab, because it teleports Riki behind the enemy. Backstab causes any attack from behind to deal additional damage, and allows you to absolutely flatten weaker enemies. If they turn to run, Riki suddenly hits for much more. Finally, Riki's Permanent Invisibility allows him to go completely invisible after a short delay. If Riki's enemies don't have any form of revelation, this lets Riki escape with ease and roam freely. If they do, Riki has to rely on his cunning and speed in order to get the drop on enemies, and get out alive.

Tips

 * It is usually recommended to get Permanent Invisibility as soon as possible.
 * Casting Smoke Screen after using Blink Strike will stop enemies from escaping or fighting back after a sudden attack.
 * Although chasing enemies might be useful, it is recommended not to be too reckless. If Riki is revealed, he can go down very quickly.
 * Blink Strike can target allies and enemies. Jumping to a friendly unit can be useful in case Rikimaru needs to escape.
 * Using items will drop Riki's invisibility. Caution is advised when using a Magic Wand while invisible.

Trivia

 * Riki's name in Dota Allstars's Fun Mode was Riki Martin, a reference to Ricky Martin, a pop singer.
