For games on Discord there is now a free O.D.I.N. bot. /roll rolls checks with white and coloured dice, with successes, excess, fumbles and a bonus die button. /table rolls on one of the 281 random tables from the books, from names and places to artefacts. /threat shows the GM the stats from the Threat Atlas, visible only to them, and rolls attacks secretly. /rule looks up rules.
Add the bot to a server or just for yourself, then it works in every server and in direct messages. You can try it in the radio room.
