Toolbox

Toolbox is a term used to describe characters who take skills that are necessary for the party, but for which the party doesn't have room elsewhere. For example, in many Heroes' Ascent builds not featuring Warriors or Paragons, Elementalists will carry the necessary "Make Haste!" and Song of Concentration, though the skills don't assist the Elementalist in filling their primary role as a damage dealer. Other examples included Rangers with Rend Enchantments, Signet of Binding, or Ward Against Foes and Grasping Earth.

Not to be confused with utility or bitchrole: for example, a Warrior may take Shock for utility, but largely for assistance in fulfilling their primary role of doing damage and creating disruption.
