Ironman Mode - The RuneScape Wiki

Ironman Mode and Hardcore Ironman Mode are account-types that encourage the player to be entirely self-sufficient. Both types of Ironman mode are locked out of most forms of interactions with other players such as trading, the Grand Exchange, most group minigames, PvP, Treasure Hunter and almost all other group activities. The modes were released on 13 October 2014. They are accessible only via the Play Mode button on the character creation screen.
