There are two different "Rune of Attraction". They're supposed to be used in two different research recipes (Levitate and Gravity Flux). It looks to me it's classic, as you can find sources (dated 2000) that confirms the existence of 2 different runes of attraction (marked as Beza and Azia) :

As for combines, i'm not sure about the Levitate combine (i don't remember if i bought it from merchant or if i researched it), but i can confirm Gravity Flux combine was working fine a year ago (it would work with the proper version of the rune of attraction).
