You basically wrote few wrong numbers about rebates and a lot about freezing which is not worth, since now you can get adv.refines from various places. Limited time items does not count in any rebate. Charms rebate is worth only when you have 500. Refines rebate worth only when you have 800 refines (I don't really understand what did you wrote about it, looks like copy/paste out of contest). 300 seals is best rebate for getting extra seals scrolls. But if this is "advanced" tips, then 800 rebate is best, since you want to collect Hashi frags from whenever you can. There's nothing useful in treasures that someone would want. Strategy towards these rebates is written by ICEx in other threads. You should try harder if you want to make guides, or leave it to those who actually know how to do it.
