Solo capper

From Guild Wars Wiki

A solo capper is a player in Alliance Battles with a build designed to kill all of the NPCs at a shrine and capture it without assistance. A shrine being capped by a single player takes longer to capture, but has the advantage of freeing up the other members of his or her team for other tasks. Most builds designed to solo cap are Elementalists using Fire Magic's AoE spells, or Monks using Ray of Judgement. Solo capping could also refer to the Mines in Fort Aspenwood or the Quarries in Jade Quarry.
