All the fruits are great for the discount it gives, but the most bought or sought after fruit is the one that gives Cave Key Gift Pack. Depends on really what you need and if you are going for power or ninjas. Cave keys are great for power!

Cave key is Great deal . other i dont think soo .

Seal scroll cost 125, but in reality almost nobody ever buys it like that, only ones who do are the super ptw.

The cave key, however, is a very nice power boost. And the ratio of key to coupon here is only second to wishing tree, which only gives a limited amount. I'd say you should buy it if you have any rune that is lv 5 or below still. If they are all 6+ thou, diminishing return is hitting hard and it's no longer worthwhile to buy keys at all, just keep harvesting the trees.

Hi PraiseLuka, how many coupons / cave keys are you harvesting from your tree and what level is it?

the only levels of tree that aren't worth the cave keys are 5 for certain as it gives 11 coupons or 1 key(buy 50 keys at once and they are 10.2 coupons a key) and arguably 4 since it gives 1 key for 9 coupons and some events give keys for less this one which gives 88 keys and 1 lvl 5 rune for 800 coupons which is 9.09 coupons a key but u also get the rune which adds better value.

lvl 1-3 dont offer keys so of course u take coupons.

Lv 10, so that's 21:4, which is 5.25 coupon per.

Barring lv 12, which will take 2+ years to get, this is the best ratio. Lv 12 would be 5:1

Thanks Luka, I'm currently only lvl 8 so its 17:3 for me.

I'm taking coupons instead and hoping to only get cave keys from mystery fruit solely due to the free level 5 rune.

Am i doing it wrong? Should i be taking cave keys instead?

On average, it takes about 20 keys to get runes which sum up to a lv 5 rune. (granted, it would be different types, but think of it this way, 100 keys will get you runes of each type which sum up to one of each, and random lv 5 rune times 5 is same, one of each, on average. Ergo, each 20 key is about equal to a lv 5 rune)

Ergo, the fruit is worth around 110 keys, for 800 coupon. This have a ratio of about 7 coupon per key

On the other hand, 17:3 have a ratio of 5.67 coupon per key

So if you are buying the fruit, you are doing it wrong.

Thanks alot for the input Luka, i get what you mean now.
