Few A few examples have yet been given for how specific skills are affected by runes socketed into them. Since each rune is (as best we know) going to work with every active skill, the hydra rune will (presumably) add a similar bonus to every other active skill in the game. Multiple impacts to melee hits, multiple charges to lightning spells, etc. All of these functions are subject to modification or change during the continuing development process.  ===Witch Doctor: Skull of Flame=== A hydra rune adds extra bounces to the [[Witch Doctor]]'s thrown Skull of Flame spell. This one was shown at a presentation at [[Blizzcon 2008]] (October), and the rune caused each thrown Skull of Flame to bounce several times, dealing additional explosive fire damage each time. Nothing is known about how many bounces this rune would add with each quality level, if each hit deals the full or somewhat reduced damage, if there are additional mana costs, etc. All those issues will be resolved with further play testing. [[Image:skullofflame_multistrike.jpg|center]]  ===Wizard: Mirror Image=== When a hydra rune is socketed in the [[Wizard]]'s]] [[Mirror Image]] skill, the number of duplicates created is increased. (October 2008.)  ===Wizard: Teleport=== A hydra rune added to the [[Teleport]] skill causes a temporary duplicate of the Wizard to be created when the Wizard teleports. The duplicate draws enemy attention for as long as it persists. (October 2008.)[[Image:teleport_multistrike.jpg|center]]  ===Wizard: Electrocute===  This skill is boosted considerably with a hydra rune, turning it into a sort of chain lightning, with the sizzling bolt hopping to lock onto and cook additional targets.
