Daniel Ray Stemkoski (born April 6, 1983), better known by his nickname Artosis, is an American professional esports commentator and Twitch streamer.

[1] As his StarCraft habits began to affect his life, his parents confiscated his dial-up modem and computer peripherals, which he circumvented with replacements.

[1] He represented North America twice at the StarCraft World Championships, and competed in the United States finals eight times.

[1] Artosis was later approached by Korean broadcasting company International e-Sports Group (IEG) in 2008, and accepted their offer.

[1] As StarCraft II's launch neared, Artosis and another American commentator living in Seoul, Nick "Tasteless" Plott, had individually amassed significant followings, and had the interest of commercial broadcast networks.

[1] Polygon attributed their success to their "magic" dynamic from complementary personalities, with Artosis being encyclopedic and analytic, and Plott bold and sociable.

[1] PC Gamer's Rich McCormick cited the pair in 2011 as examples of how the electronics sports profession is developing celebrities.

[1] Tasteless has said that he considers Tastosis's nuanced readings of player tactics and their eventualities as a "gateway" for bringing unfamiliar crowds into StarCraft.

[1] Artosis cast alongside Tasteless at the 2012 StarCraft II World Championship Series Europe finals,[7] Australian and Oceania finals,[8] and UK nationals,[9] DreamHack Winter 2011,[10] IGN Pro League Season Two,[11] and Major League Gaming 2012 Spring Arena,[12] Raleigh,[13][14] and 2011 Orlando.

[18] In addition, he has a secondary YouTube channel named ArtosisCasts, on which he uploads daily casts of numerous StarCraft matches that primarily involve professional players.

[20] However, through Patreon support,[21] the two were given permission to cast over VODs of the events, and have them uploaded onto the official AfreecaTV eSports YouTube channel.
