What is the story behind this rune? From what I've found on the forums, it was removed from the game at one point, but apparently it is still possible to obtain? Are there other runes like this?
It's a rune that was removed from the game indeed. You can still obtain it via Trade if someone have them. There are others runes that are even mre impossible to get that was removed from the game, I have seen someone post all of his collection of "forbiden" runes somewhere, don't remember who or when.
I've seen him too but also forgot his name. he owns a serkan with attack range 1-7. That's pretty bad ass.
Polymorph (rare) 65 nora cost. -4 damage, -2 speed, +Leap 1 for 3 rounds. Polymorph currently doesn't break anything. (Correct me if you think otherwise) Although i own it i think it would be nice if it would be a normal obtainable rune again. The spell transforms the target into a cuddly bunny that looks cute.
I've seen Lich Knight and Single Rider Korsien. Single Rider Korsien is(was) usable in ranked and was pretty OP.
lol korsien is horrible now. It took a year just to convince them to cost his rider ability properly and he still sucks.
They are runnes you can obtain buying stuff (polymorph). The Serkan, Single Korsien, and so many others like that I don't know how they had obtained them, but they are pretty cool.
