There are four stages of markers. They are unlocked by killing various amounts of bosses in the Dominion Tower. After killing the level 112 version of Sunfreet, horns will appear on your marker with particle effects. When placed near you, the marker offers a decaying visible boost in combat. This boost only activates when the player is hit by a monster, and only reapplies when the player's levels return to their base values. When the marker gives the stat boost you get the message "You feel proud and empowered by your marker." While deployed, it also provides an invisible prayer bonus.
