==Every Rune Works in Every Skill==

[[Jay Wilson]] has stressed that runes must add a useful function to multiple types of skills, since every type of rune will be socketable in every action skill. (As far as we know.) This leads to some odd and creative design decisions, since while it's obvious what most runes will do in most skills, there are some exceptions. Consider what a rune that adds multiple hits or damage does for a purely defensive/shielding skill? Or a movement skill like the Wizard's Teleport?

The [[D3 Team]] wants all the runes to be useful to all [[class]]es, so they did not add runes that just boosted one type of skill, or one character's skills. They had to find general function bonuses that worked across the board, which is why there are not fifty types of runes. Instead there are just five rune types, though even with just 5, their functions change quite a bit from skill to skill, in many cases.
