Before Winter Update 2007, this rune required 720 mana to be made and had only 3 charges. Explosion is the only Spell for mages which inflicts Physical Damage, since the Winter Update 2007, when the Ultimate Explosion spell changed its name to Hell's Core and its damage turned to Fire Damage, the Force Strike spell changed from Physical Damage to Death Damage, and the Sudden Death rune became a Death Damage rune.
