Rune Of Crystal 5lvl

i have rune of crystal 5lvl - 7day.
it works with my main character. but when i switch to sub-class it stops working. is it some kind of bug or what?
i paid money for it to have easier sub-class leveling and i don't get a needed result. can someone explain me why is that so?

 

level of sub and equip you're trying to wear? :s

 

let me guess, he's trying to wear s-grade at level 40. :d

 

yeh, same thinking.

in case you're trying to use s grade at lv40 then you're doing it wrong. with this rune you can do this:
- use d at lv15,
- c at lv35,
- b at lv47,
- a at lv56,
- s at lv71 and
- s80 at lv75.

in case you're doing it right after all, i guess support is the only option. :s

 

how about r grade at 80?that would be useful at least.

 

actually r grade @ level 70 )

thank you. this was very usefull

 

question answered. moving thread to archives.
