I found a Jah in Pits Hell and needed it to make my first Infinity... and when i put it into cube and transmuted it gave me Sur Ber -.- Lol i can't even turn it back into a Jah now >.<
We have here some improvements / changes. You can find it here : http://forum.europebattle.net/threads/full-list-of-custom-features-and-recipes.523720/
Also, keep in mind that runes breaking or downgrading is not an original game feature but a custom one that we implemented. You can break every rune up to ber into two equal lower runes, however, if you wish to break higher runes than that there will be a fee for it but this only opens trading possibilities even more. You can sell a Jah rune for Ber + Sur + Lo to other players or if you're in a rush cube it and get Ber + Sur instantly which is miles better than trading the same rune for another single lower one as you would normally have to do in the original game for example since it doesn't allow runes breaking.
The idea is to stimulate trade. Usually you can trade a Jah down to a Ber Sur Lo. It would ruin the whole economy. Image a Zod worth 4 Jah?!
