I agree. Spending coupons on magatamas as free to play is one of the worst things to do when they come free everyday. Sure the progress is slower, but you'll still get there.

There are better and cheaper things to spend coupons on for free to play players.

Bounty missions? Do you mean the monthly event where you level up 10 magatamas? If you do, then you can just use level 1s to upgrade into level 2 and so forth.

I save coupons for events like treasure of sage where you can get discounted items. Usually go for items that I need like refines, mood scrolls, tactics, thread. Mood scrolls are really cheap power. Tactics are really good for power as well, but it's risky since the system is like refines and armor. Refines aren't good for power, but they do help you to get a slight advantage in fights.

Usually choose the cheapest power item or what you need the most of at that time. Purification runes are pretty cheap, but they're risky too and may need a large stockpile if you're unlucky like I am.

You're welcome. I hope I helped in some way. ^^ Good luck with your strengthening.

That is interesting, I haven't received any type of mission to buy something from the store.

Ooh, I know what you're talking about now. I forgot about those because I never did them. xD They were a waste to me so I just waited for a good mission that I liked/wanted.
