The skull is a status effect in RuneScape. The skull appears for players attacking another in the Wilderness, or if they enter the Abyss and they do not have an abyssal bracelet equipped. Players can also get a skull without having to use either method by asking the Emblem Trader to skull them. When skulled, you will lose all items upon death, unless the Protect Item prayer is used, in which case you will keep your most valuable item upon death.
Players who are attacked by another player in the Wilderness can safely retaliate without getting skulled themselves. However, innocent players entering the Wilderness should be careful for "skull trickers". Skull trickers will attempt to skull you through exploiting in-game mechanics, since most players entering the Wilderness are usually there to kill monsters or collect resources.
Note: In multi-way areas, you can unintentionally skull yourself with AoE attacks (e.g burst/barrage spells, chinchompas) if you use it against the aggressor and there are other players that haven't attacked you first next or on them.
The "skull" will disappear automatically after 10/20 minutes depending on how the player got it; it disappears after 10 minutes after using the Abyss, and 20 after attacking a player. If you re-enter the Abyss or attack another player that has not attacked you yet, the skull timer will reset.
If a player needs to quickly remove their skull, they can either go to monster(s) which will kill them very quickly (such as the Corporeal Beast) or a player can enter the free-for-all portal at Clan Wars and then leave.
- In RuneScape Classic, getting marked with a skull was officially known as setting one's alignment to Evil.
- The skull is said to be the mark of Zamorak during the Enter the Abyss miniquest.
- Sir Renitee asks for the player to be skulled for switching to the "Skull" family crest.
