AP/SP Reset Giveaway Question

Quick question about this event.
If i make any char and get it to 30, can i use the resets on any other char on the same acc?
Also is there a limit to this?

If the char you make is a regular explorer (not Dual Blade), the resets you get are in the shared cash shop storage with the other regular explorers on the account, so you can use them on those chars.
You can't use them on Knights of Cygnus, Aran, Evan, or Dual Blades, as each char of those classes has its own cash shop storage.

There is a limit. You can only receive each AP reset package (level 30, 50, and 70) once per account. So the maximum AP resets you can get is 45, and maximum SP resets is 10 2nd job, 20 3rd job.
