I get charms pack, unbound rune pack and krabby frag.

Reason:

I'm almost done with medium refine, I have all of 2 gears at 6. And I have over 100 medium refine, so there is a good chance I don't need anymore of them, even if I do, I can get it from monthly on demand.

Hence the unbound rune pack.

The krabby thing is related. Due to I'm being mostly done with medium refine, my monthly is going toward either ninja frags or seal/summon scroll, depending on ninja being offered. This particular month, it's scrolls. I have all the regular golds, just no turtle/krab/KoH/kirin, so summon scroll is meh on that front. And as far as getting runes as well as shop credits for rune goes, I'm all lv 8 on runes now, and even a 100 pull during rebate will only give me 100-200 power on that front. So summon scroll, aside from eventually getting me KoH or Kirin, is very meh. Ergo, I might as well start collecting krab since that's more or less the same thing (that is to say to get a new summon).

On a side note, I'm at lv 8 92/120 exp on cultivation, and I still have a LOT of sub 100 priced option to go for. I'm guessing you just don't have a lot of gold summon, so you have to go for higher tier cultivation which cost more. If you had more summons, you only need half of the 4th circle on the golds to level up to 7 and 8, even 9 actually. 10 probably will need going beyond that since there are no more gold being level locked
