Ironman Mode is an account-type that encourages the player to be entirely self-sufficient. Ironmen are locked out of most forms of interactions with other players such as trading, the Grand Exchange, most group minigames, PvP, and almost all other group activities.

ronman players are not able to do the following:

Trade with other players (except certain quest items from Shield of Arrav and Heroes Quest) Pick up drops from other players' kills, including PvP No loot will drop whatsoever if another player has dealt damage to that monster. Even one point of damage dealt by a non-ironman player will prevent the ironman from getting any loot. This does not apply if that monster was weakened by other monsters. Gain experience from player-versus-player encounters (base Magic experience from casting spells is still gained, however) Use the Accept Aid feature Enter another player's player-owned house Buy items from other players through overstocked shops or take advantage of higher sell prices of understocked shops Receive items via balloons in the Falador Party Room Stake in the Duel Arena Group activities in Nightmare Zone, and resource rewards from the reward chest (excluding scroll of redirection)
