Riki is a squishy yet effectively agility melee hero who excels at silencing with Smoke Screen then dealing tons of damage with Blink Strike and Backstab. Riki is a cunning hero able to escape with the awesome ult and passive Permanent Invisibility which is a really useful tool for escaping and preparing to attack. This guide is a general outline on how to use Riki.
Riki was born middle child to the great dynasty of Tahlin. With an older brother groomed for the throne, and a younger brother coddled and kept, Riki, the small middle son, seemed born for the art of invisibility. It was an art he cultivated, and one which ultimately saved his life on the night that his people were betrayed and his family slaughtered. Of all the royal line, he alone escaped-small and agile, unassuming, using smoke as cover. He cut his way out of the royal grounds, using the advantage of surprise, quietly slitting the throats of one enemy warrior after another. Now free of his royal responsibilities, Riki uses his talents in service to a new trade: Stealth Assassin. He silences his enemies, sharpening his skills, hoping to one day take revenge on those who killed his family and robbed him of his birthright.
-Great escape mechanism with Permanent Invisibility and Blink Strike
-Good attack speed
-Great for chasing down heroes with Blink Strike
-Casting Smoke Screen and Blink Strike sounds awesome!!!
-Usually runs out of mana if you harass with Blink Strike
-Countered by Observer Ward, Sentry Ward, Gem of True Sight]] and Necronium Book(level 3 only)
-Hitting creeps behind will then trigger Backstab(kind of obvious)
Throws down a smoke bomb, silencing and slowing enemy units in an area while causing them to miss on most attacks. Lasts 6 seconds.
Ability: Target Point
Miss Chance: 40%/50%/60%/70%
Attack and Movement Speed Slow: 25%
Mana cost: 75/80/85/90
-Does not silence castable items
This will help you avoid magical damage when you cast this on yourself and on the enemy. They will be silenced and have a high chance of missing attacks while you can harass or gank them. Use this to initiate one on one battles or team clashes. This can be used with Mask of Madness for EXTREME dps!!!
For my Ordinary Starting Items, I have a Stout Shield to stop earlier harassment received by enemy heroes and creeps. Slippers of Agility is used to deny and last his more effectively and can be later made in to a Poor Man's Shield. The 2 Tangos are used to counter medium to light harassment.
For Early Game, I have a Poor Man's Shield to again last his and deny more effectively as well as preventing 20 damage received from heroes, allowing you to gank more efficiently. Boots of Speed are essential for all heroes to increase movement speed. Belt of Strength is to counter your squishiness, giving you 114 health. This can be later built into Power Treads. Instead of Belt of Strength, you can have a Boots of Elvskin if you are careful in avoiding harassment and want a higher dps.
For Core, i have Power Treads to choose what attribute I want when i need it. Health for hp regen and an additional health pool, Agility for a higher dps and Intelligence for mana regen and an additional mana pool. When healing at the fountain, turn your boots to agility if they were strength or intelligence for faster hp and mana regen. Vladmir's Offering improves pushing power, mana regen, bonus damage, hp regen, armour and 16% lifesteal. This is used to receive health back for Riki. Quarterstaff and Talisman of Evasion are used to build Butterfly, which greatly benefits you.
Butterfly is for late game as it provides 60 attack speed, 60 damage and 35% evasion for Riki. Sange and Yasha provides everything which you want for an agility hero, like Riki. All the situational items are obviously situational.
I will later expand on this area
Allies for Rikimaru are those who can become invisible for the element of surprise or those heroes who can melt armour to take in extra damage. These guys are Templar Assassin, Sladar, Bounty Hunter, Weaver and some other heroes.
Enemies are those who have Gem of True Sight or Dust of Appearance, or they are Sladar and Bounty Hunter with their ultimates. A special mention is Wisp because he has no backside?!?!?
Rikimaru is overall a fun hero can troll people. Please feel free to add any comments :D
