The spell is sometimes used alongside various other Barrage spells, such as Ice Barrage, in multi-combat PvP activities. This method is normally used by players with high Magic, Defence, and Hitpoints levels.
The spell is also used by players to extend longevity at a dangerous location. In the God Wars Dungeon, Blood Barrage is ideal for healing on bodyguards, such as Tstanon Karlak and Zakl'n Gritch in K'ril Tsutsaroth's chamber, as well as on Flight Kilisa and Flockleader Geerin in Kree'arra's chamber after their corresponding general is defeated, to conserve supplies. It is a popular spell to use in the Inferno mini game, the smaller clumped monsters work best, like such as nibblers or bloblets (Jal-AkRek-Ket, Jal-AkRek-Xil, and Jal-AkRek-Mej). Some players also use it on Spinolyps at Dagannoth Kings.
