Show/Hide Tooltips

Remains permanently invisible until the moment to strike.
Leaving his past life behind, Riki escaped the royal grounds using his own Cloak-and-Dagger methods. Stealthy and fond of killing from behind, Riki throws down a dense Smoke Screen, blinding and choking foes as he takes them by surprise with Blink Strike. Intruders who enter his turf is greeted with twin daggers, flashes of steel that slash simultaneously at every turned back while the master himself remains unseen. How this feat is accomplished remains a mystery, for the Stealth Assassin is not one to divulge his Tricks of the Trade.

Bio

There are none so stabbed as those who will not see.

▶️  Riki, the Stealth Assassin

Aliases:

SA, Stealth Assassin

Lore:

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.
