"Recruit a friend" code thread - New player exp boosts!

[Niwashi]

If I use my friends code and then add 90 reoccurring sub do they get the 90 reward right away or only if I used 30,30,30 game cards?
What is the best way to get the increased exp right out of the gate (or after the trial). I will be using Steam Retail.

Your friend will get the 90 day reward as soon as you've actually paid for extending your sub by a total of 90 days (regardless of whether that's done all at once or in multiple installments). An issue with the credit card or crysta recurring sub is that, even if you set it up immediately, the payment is only deducted from your card or crysta balance once it's actually due. This means no payments are made until the 30 days included with purchase run out. In financial terms this is generally a good thing, but it delays any rewards based on that payment, like these Recruit A Friend bonus items and the Veteran bonuses.

When buying Game Time Cards, payment is made to the third party retailer you purchase it from, which gives you control over the timing. You're credited with actual payment (and therefore can get rewards) as soon as you register that card to your account at the MogStation. I'm not sure whether there are 30 or 90 day cards, though. I've only seen the 60 day ones. If 60 is the only card interval, you'd have to overshoot the 90 requirement by getting two of them before your friend gets the 90 day mount reward.

also is the Increases EXP earned by 20% when level 25 and below permanent?

It's a property of the Friendship Circlet. Any time you're on a class that's level 25 or below and have that circlet equipped, you get the EXP bonus. (It does mean foregoing any other bonuses you might have gotten from equipping different headgear, though.) Since there's a lot of multi-classing in this game and each class has its own level, you may well end up getting your first class all the way to 50 while having alt classes that are still under 25, and the circlet would still work for those lower level alt classes.
