I bought a paladin job skip for my old character as id already levelled it to 60 on my legacy char, but now im maining my legacy char again.

Now i was wandering, as i cant quite understand the wording of the job skip item.. Would it be possible for me to buy a summoner job skip potion for my lecgacy char even though ive purchased the paladin one?

"You may only purchase one job-specific Tales of Adventure item per service account.
Moreover, this item can only be used on one character. "

To me this is saying "you can literally only buy one" not one of each job .. and as refunds wont be given upon a mistake of purchase, can someone shed some light on this?

Again, reason for buying this is because ive already levelled smn pretty high on my old char. Back in the day of 2.0 there was no server switching and my friends decided to start on a fresh one -.-
