It was not possible to cut the cost of water blast (and its variables) to zero, since staff of air (and equivalent staff) must be held in both hands nowadays. However, as of 4 August, 2014, one can wield the Avernic wand and a tome of frost to reduce the cost to zero. Even before release of Evolution of combat, while both items can be equipped at the same time, Water Blast requires an additional death rune.
